[This post was originally published on June 9, 2017]

Last autumn, U.S. Army Chief of Staff General Mark Milley asserted that “we are on the cusp of a fundamental change in the character of warfare, and specifically ground warfare. It will be highly lethal, very highly lethal, unlike anything our Army has experienced, at least since World War II.” He made these comments while describing the Army’s evolving Multi-Domain Battle concept for waging future combat against peer or near-peer adversaries.

How lethal will combat on future battlefields be? Forecasting the future is, of course, an undertaking fraught with uncertainties. Milley’s comments undoubtedly reflect the Army’s best guesses about the likely impact of new weapons systems of greater lethality and accuracy, as well as improved capabilities for acquiring targets. Many observers have been closely watching the use of such weapons on the battlefield in the Ukraine. The spectacular success of the Zelenopillya rocket strike in 2014 was a convincing display of the lethality of long-range precision strike capabilities.

It is possible that ground combat attrition in the future between peer or near-peer combatants may be comparable to the U.S. experience in World War II (although there were considerable differences between the experiences of the various belligerents). Combat losses could be heavier. It certainly seems likely that they would be higher than those experienced by U.S. forces in recent counterinsurgency operations.

Unfortunately, the U.S. Defense Department has demonstrated a tenuous understanding of the phenomenon of combat attrition. Despite wildly inaccurate estimates for combat losses in the 1991 Gulf War, only modest effort has been made since then to improve understanding of the relationship between combat and casualties. The U.S. Army currently does not have either an approved tool or a formal methodology for casualty estimation.

Historical Trends in Combat Attrition

Trevor Dupuy did a great deal of historical research on attrition in combat. He found several trends that had strong enough empirical backing that he deemed them to be verities. He detailed his conclusions in Understanding War: History and Theory of Combat (1987) and Attrition: Forecasting Battle Casualties and Equipment Losses in Modern War (1995).

Dupuy documented a clear relationship over time between increasing weapon lethality, greater battlefield dispersion, and declining casualty rates in conventional combat. Even as weapons became more lethal, greater dispersal in frontage and depth among ground forces led daily personnel loss rates in battle to decrease.

The average daily battle casualty rate in combat has been declining since 1600 as a consequence. Since battlefield weapons continue to increase in lethality and troops continue to disperse in response, it seems logical to presume the trend in loss rates continues to decline, although this may not necessarily be the case. There were two instances in the 19th century where daily battle casualty rates increased—during the Napoleonic Wars and the American Civil War—before declining again. Dupuy noted that combat casualty rates in the 1973 Arab-Israeli War remained roughly the same as those in World War II (1939-45), almost thirty years earlier. Further research is needed to determine if average daily personnel loss rates have indeed continued to decrease into the 21st century.

Dupuy also discovered that, as with battle outcomes, casualty rates are influenced by the circumstantial variables of combat. Posture, weather, terrain, season, time of day, surprise, fatigue, level of fortification, and “all out” efforts affect loss rates. (The combat loss rates of armored vehicles, artillery, and other other weapons systems are directly related to personnel loss rates, and are affected by many of the same factors.) Consequently, yet counterintuitively, he could find no direct relationship between numerical force ratios and combat casualty rates. Combat power ratios which take into account the circumstances of combat do affect casualty rates; forces with greater combat power inflict higher rates of casualties than less powerful forces do.

Winning forces suffer lower rates of combat losses than losing forces do, whether attacking or defending. (It should be noted that there is a difference between combat loss rates and numbers of losses. Depending on the circumstances, Dupuy found that the numerical losses of the winning and losing forces may often be similar, even if the winner’s casualty rate is lower.)

Dupuy’s research confirmed the fact that the combat loss rates of smaller forces is higher than that of larger forces. This is in part due to the fact that smaller forces have a larger proportion of their troops exposed to enemy weapons; combat casualties tend to concentrated in the forward-deployed combat and combat support elements. Dupuy also surmised that Prussian military theorist Carl von Clausewitz’s concept of friction plays a role in this. The complexity of interactions between increasing numbers of troops and weapons simply diminishes the lethal effects of weapons systems on real world battlefields.

Somewhat unsurprisingly, higher quality forces (that better manage the ambient effects of friction in combat) inflict casualties at higher rates than those with less effectiveness. This can be seen clearly in the disparities in casualties between German and Soviet forces during World War II, Israeli and Arab combatants in 1973, and U.S. and coalition forces and the Iraqis in 1991 and 2003.

Combat Loss Rates on Future Battlefields

What do Dupuy’s combat attrition verities imply about casualties in future battles? As a baseline, he found that the average daily combat casualty rate in Western Europe during World War II for divisional-level engagements was 1-2% for winning forces and 2-3% for losing ones. For a divisional slice of 15,000 personnel, this meant daily combat losses of 150-450 troops, concentrated in the maneuver battalions (The ratio of wounded to killed in modern combat has been found to be consistently about 4:1. 20% are killed in action; the other 80% include mortally wounded/wounded in action, missing, and captured).

It seems reasonable to conclude that future battlefields will be less densely occupied. Brigades, battalions, and companies will be fighting in spaces formerly filled with armies, corps, and divisions. Fewer troops mean fewer overall casualties, but the daily casualty rates of individual smaller units may well exceed those of WWII divisions. Smaller forces experience significant variation in daily casualties, but Dupuy established average daily rates for them as shown below.

For example, based on Dupuy’s methodology, the average daily loss rate unmodified by combat variables for brigade combat teams would be 1.8% per day, battalions would be 8% per day, and companies 21% per day. For a brigade of 4,500, that would result in 81 battle casualties per day, a battalion of 800 would suffer 64 casualties, and a company of 120 would lose 27 troops. These rates would then be modified by the circumstances of each particular engagement.

Several factors could push daily casualty rates down. Milley envisions that U.S. units engaged in an anti-access/area denial environment will be constantly moving. A low density, highly mobile battlefield with fluid lines would be expected to reduce casualty rates for all sides. High mobility might also limit opportunities for infantry assaults and close quarters combat. The high operational tempo will be exhausting, according to Milley. This could also lower loss rates, as the casualty inflicting capabilities of combat units decline with each successive day in battle.

It is not immediately clear how cyberwarfare and information operations might influence casualty rates. One combat variable they might directly impact would be surprise. Dupuy identified surprise as one of the most potent combat power multipliers. A surprised force suffers a higher casualty rate and surprisers enjoy lower loss rates. Russian combat doctrine emphasizes using cyber and information operations to achieve it and forces with degraded situational awareness are highly susceptible to it. As Zelenopillya demonstrated, surprise attacks with modern weapons can be devastating.

Some factors could push combat loss rates up. Long-range precision weapons could expose greater numbers of troops to enemy fires, which would drive casualties up among combat support and combat service support elements. Casualty rates historically drop during night time hours, although modern night-vision technology and persistent drone reconnaissance might will likely enable continuous night and day battle, which could result in higher losses.

Drawing solid conclusions is difficult but the question of future battlefield attrition is far too important not to be studied with greater urgency. Current policy debates over whether or not the draft should be reinstated and the proper size and distribution of manpower in active and reserve components of the Army hinge on getting this right. The trend away from mass on the battlefield means that there may not be a large margin of error should future combat forces suffer higher combat casualties than expected.

1st Security Force Assistance Brigade To Deploy To Afghanistan In Spring

The U.S. Army recently announced that the newly-created 1st Security Force Assistance Brigade (SFAB) will deploy to Afghanistan under the command of Colonel Scott Jackson in the spring of 2018 in support of the ongoing effort to train and advise Afghan security forces. 1st SFAB personnel formed the initial classes at the Military Advisor Training Academy (MATA) in August 2017 at Fort Benning, Georgia; approximately 525 had completed the course by November.

The Army intends to establish five Regular Army and one Army National Guard SFABs. In December it stated that the 2nd SFAB would stand up in January 2018 at Fort Bragg, North Carolina.

The Army created the SFABs and MATA in an effort to improve its capabilities to resource and conduct Security Force Assistance (SFA) missions and to relieve line Brigade Combat Teams (BCTs) of these responsibilities. Each SFAB will be manned by 800 senior and noncommissioned volunteer officers with demonstrated experience training and advising foreign security forces.

Specialized training at MATA includes language, foreign weapons, and the Joint Fires Observer course. SFAB commanders and leaders have previous command experience and enlisted advisors hold the rank of sergeant and above. As of August 2017, recruiting for the first unit had been short by approximately 350 personnel, though the shortfall appears to have been remedied. The Army is working to address policies and regulations with regard to promotion rates and boards, selection boards, and special pay.in order to formalize a SFAB career path

The Principle Of Mass On The Future Battlefield

Given the historical trend toward battlefield dispersion as a result of the increasing lethality of weapons, how will the principle of mass apply in future warfare? I have been wondering about this for a while in the context of the two principle missions the U.S. Army must plan and prepare for, combined arms maneuver and wide area security. As multi-domain battle advocates contend, future combat will place a premium on smaller, faster, combat formations capable of massing large amounts of firepower. However, wide area security missions, such as stabilization and counterinsurgency, will continue to demand significant numbers of “boots on the ground,” the traditional definition of mass on the battlefield. These seemingly contradictory requirements are contributing to the Army’s ongoing “identity crisis” over future doctrine, training, and force structure in an era of budget austerity and unchanging global security responsibilities.

Over at the Australian Army Land Power Forum, Lieutenant Colonel James Davis addresses the question generating mass in combat in the context of the strategic challenges that army faces. He cites traditional responses by Western armies to this problem, “Regular and Reserve Force partnering through a standing force generation cycle, indigenous force partnering through deployed training teams and Reserve mobilisation to reconstitute and regenerate deployed units.”

Davis also mentions AirLand Battle and “blitzkrieg” as examples of tactical and operational approaches to limiting the ability of enemy forces to mass on the battlefield. To this he adds “more recent operational concepts, New Generation Warfare and Multi Domain Battle, [that] operate in the air, electromagnetic spectrum and cyber domain and to deny adversary close combat forces access to the battle zone.” These newer concepts use Cyber Electromagnetic Activities (CEMA), Information Operations, long range Joint Fires, and Robotic and Autonomous systems (RAS) to attack enemy efforts to mass.

The U.S. Army is moving rapidly to develop, integrate and deploy these capabilities. Yet, however effectively new doctrine and technology may influence mass in combined arms maneuver combat, it is harder to see how they can mitigate the need for manpower in wide area security missions. Some countries may have the strategic latitude to emphasize combined arms maneuver over wide area security, but the U.S. Army cannot afford to do so in the current security environment. Although conflicts emphasizing combined arms maneuver may present the most dangerous security challenge to the U.S., contingencies involving wide area security are far more likely.

How this may be resolved is an open question at this point in time. It is also a demonstration as to how tactical and operational considerations influence strategic options.

U.S. Army Swarm Offensives In Future Combat

For a while now, military pundits have speculated about the role robotic drones and swarm tactics will play in future warfare. U.S. Army Captain Jules Hurst recently took a first crack at adapting drones and swarms into existing doctrine in an article in Joint Forces Quarterly. In order to move beyond the abstract, Hurst looked at how drone swarms “should be inserted into the tactical concepts of today—chiefly, the five forms of offensive maneuver recognized under Army doctrine.”

Hurst pointed out that while drone design currently remains in flux, “for assessment purposes, future swarm combatants will likely be severable into two broad categories: fire support swarms and maneuver swarms.”

In Hurst’s reckoning, the chief advantage of fire support swarms would be their capacity for overwhelming current air defense systems to deliver either human-targeted or semi-autonomous precision fires. Their long-range endurance of airborne drones also confers an ability to take and hold terrain that current manned systems do not possess.

The primary benefits of ground maneuver swarms, according to Hurst, would be their immunity from the human element of fear, giving them a resilient, persistent level of combat effectiveness. Their ability to collect real-time battlefield intelligence makes them ideal for enabling modern maneuver warfare concepts.

Hurst examines how these capabilities could be exploited through each of the Army’s current schemes of maneuver: infiltration, penetration, frontal attack, envelopment, and the turning maneuver. While concluding that “ultimately, the technological limitations and advantages of maneuver swarms and fire support swarms will determine their uses,” Hurst acknowledged the critical role Army institutional leadership must play in order to successfully utilize the new technology on the battlefield.

U.S. officers and noncommissioned officers can accelerate that comfort [with new weapons] by beginning to postulate about the use of swarms well before they hit the battlefield. In the vein of aviation visionaries Billy Mitchell and Giulio Douhet, members of the Department of Defense must look forward 10, 20, or even 30 years to when artificial intelligence allows the deployment of swarm combatants on a regular basis. It will take years of field maneuvers to perfect the employment of swarms in combat, and the concepts formed during these exercises may be shattered during the first few hours of war. Even so, the U.S. warfighting community must adopt a venture capital mindset and accept many failures for the few novel ideas that may produce game-changing results.

Trevor Dupuy would have agreed. He argued that the crucial factor in military innovation was not technology, but the organization approach to using it. Based on his assessment of historical patterns, Dupuy derived a set of preconditions necessary for the successful assimilation of new technology into warfare.

  1. An imaginative, knowledgeable leadership focused on military affairs, supported by extensive knowledge of, and competence in, the nature and background of the existing military system.
  2. Effective coordination of the nation’s economic, technological-scientific, and military resources.
    1. There must exist industrial or developmental research institutions, basic research institutions, military staffs and their supporting institutions, together with administrative arrangements for linking these with one another and with top decision-making echelons of government.
    2. These bodies must conduct their research, developmental, and testing activities according to mutually familiar methods so that their personnel can communicate, can be mutually supporting, and can evaluate each other’s results.
    3. The efforts of these institutions—in related matters—must be directed toward a common goal.
  3. Opportunity for battlefield experimentation as a basis for evaluation and analysis.

Is the U.S. Army up to the task?

Gulf War Records

We, of course, have never examined the other sides records for the Gulf War (1990-91). We have included in our various combat databases over 20 division and battalion-level engagements from the Gulf War. These were all assembled for us by C. Curtis Johnson, former VP of HERO and author of something like eight books.

At the time he was working for a project that had collected the U.S. Gulf War records. So he had access to the U.S. records of the various engagements, as was able to assemble the U.S. side. He had to assemble the estimates of Iraqi strength and losses based upon the U.S. intelligence records and a little educated guesswork. There are real problems in using intelligence estimates to determine the other side’s strength and losses. I can point out a number of cases where loss estimates were off by an order of magnitude (I discuss this in depth in my Kursk book). Still, as we had overrun most of the units involved, taking their records at the time, then it appears that these were reasonable and the certainly the best estimates that could be made at the time. Because the records Curt was working with were classified, and our database is unclassified, he could not leave a record of how he developed these estimates. There were, of course, also problems with the U.S. records, but that is the subject of another post.

Now, our engagements could be improved upon by a careful examination of the captured Iraqi records, which is why this caught our attention:

The Sad Story Of The Captured Iraqi DESERT STORM Documents

Needless to say, this means that for all practical purposes, the 20+ engagements in our database can never be cross-checked or improved upon. It is the best that can be done.

The Historical Combat Effectiveness of Lighter-Weight Armored Forces

In 2001, The Dupuy Institute conducted a study for the U.S. Army Center for Army Analysis (CAA) on the historical effectiveness of lighter-weight armored forces. At the time, the Army had developed a requirement for an Interim Armored Vehicle (IAV), lighter and more deployable than existing M1 Abrams Main Battle Tank and the M2 Bradley Infantry Fighting Vehicle, to form the backbone of the future “Objective Force.” This program would result in development of the Stryker Infantry Fighting Vehicle.

CAA initiated the TDI study at the request of Walter W. “Don” Hollis, then the Deputy Undersecretary of the Army for Operations Research (a position that was eliminated in 2006.) TDI completed and submitted “The Historical Combat Effectiveness of Lighter-Weight Armored Forces” to CAA in August 2001. It examined the effectiveness of light and medium-weight armored forces in six scenarios:

  • Conventional conflicts against an armor supported or armor heavy force.
  • Emergency insertions against an armor supported or armor heavy force.
  • Conventional conflict against a primarily infantry force (as one might encounter in sub-Saharan Africa).
  • Emergency insertion against a primarily infantry force.
  • A small to medium insurgency (includes an insurgency that develops during a peacekeeping operation).
  • A peacekeeping operation or similar Operation Other Than War (OOTW) that has some potential for violence.

The historical data the study drew upon came from 146 cases of small-scale contingency operations; U.S. involvement in Vietnam; German counterinsurgency operations in the Balkans, 1941-1945; the Philippines Campaign, 1941-42; the Normandy Campaign, 1944; the Korean War 1950-51; the Persian Gulf War, 1990-91; and U.S. and European experiences with light and medium-weight armor in World War II.

The major conclusions of the study were:

Small Scale Contingency Operations (SSCOs)

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It would appear that existing systems (M-2 and M-3 Bradley and M-113) can fulfill most requirements. Current plans to develop an advanced LAV-type vehicle may cover almost all other shortfalls. Mine protection is a design feature that should be emphasized.
  2. Implications for the Interim Brigade Combat Team (IBCT). The need for armor in SSCOs that are not conventional or closely conventional in nature is limited and rarely approaches the requirements of a brigade-size armored force.

Insurgencies

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It would appear that existing systems (M-2 and M-3 Bradley and M-113) can fulfill most requirements. The armor threat in insurgencies is very limited until the later stages if the conflict transitions to conventional war. In either case, mine protection is a design feature that may be critical.
  2. Implications for the Interim Brigade Combat Team (IBCT). It is the nature of insurgencies that rapid deployment of armor is not essential. The armor threat in insurgencies is very limited until the later stages if the conflict transitions to a conventional war and rarely approaches the requirements of a brigade-size armored force.

Conventional Warfare

Conventional Conflict Against An Armor Supported Or Armor Heavy Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It may be expected that opposing heavy armor in a conventional armor versus armor engagement could significantly overmatch the IAV. In this case the primary requirement would be for a weapon system that would allow the IAV to defeat the enemy armor before it could engage the IAV.
  2. Implications for the Interim Brigade Combat Team (IBCT). The IBCT could substitute as an armored cavalry force in such a scenario.

Conventional Conflict Against A Primarily Infantry Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. This appears to be little different from those conclusions found for the use of armor in SSCOs and Insurgencies.
  2. Implications for the Interim Brigade Combat Team (IBCT). The lack of a major armor threat will make the presence of armor useful.

Emergency Insertion Against An Armor Supported Or Armor Heavy Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. It appears that the IAV may be of great use in an emergency insertion. However, the caveat regarding the threat of being overmatched by conventional heavy armor mentioned above should not be ignored. In this case the primary requirement would be for a weapon system that would allow the IAV to defeat the enemy armor before it could engage the IAV.
  2. Implications for the Interim Brigade Combat Team (IBCT). Although the theoretical utility of the IBCT in this scenario may be great it should be noted that The Dupuy Institute was only able to find one comparable case of such a deployment which resulted in actual conflict in US military history in the last 60 years (Korea, 1950). In this case the effect of pushing forward light tanks into the face of heavier enemy tanks was marginal.

Emergency Insertion Against A Primarily Infantry Force

  1. Implications for the Interim Armored Vehicle (IAV) Family of Vehicles. The lack of a major armor threat in this scenario will make the presence of any armor useful. However, The Dupuy Institute was unable to identify the existence of any such cases in the historical record.
  2. Implications for the Interim Brigade Combat Team (IBCT). The lack of a major armor threat will make the presence of any armor useful. However, The Dupuy Institute was unable to identify the existence of any such cases in the historical record.

Other Conclusions

Wheeled Vehicles

  1. There is little historical evidence one way or the other establishing whether wheels or tracks are the preferable feature of AFVs.

Vehicle Design

  1. In SSCOs access to a large-caliber main gun was useful for demolishing obstacles and buildings. This capability is not unique and could be replaced by AT missiles armed CFVs, IFVs and APCs.
  2. Any new lighter tank-like vehicle should make its gun system the highest priority, armor secondary and mobility and maneuverability tertiary.
  3. Mine protection should be emphasized. Mines were a major threat to all types of armor in many scenarios. In many SSCOs it was the major cause of armored vehicle losses.
  4. The robust carrying capacity offered by an APC over a tank is an advantage during many SSCOs.

Terrain Issues

  1. The use of armor in urban fighting, even in SSCOs, is still limited. The threat to armor from other armor in urban terrain during SSCOs is almost nonexistent. Most urban warfare armor needs, where armor basically serves as a support weapon, can be met with light armor (CFVs, IFVs, and APCs).
  2. Vehicle weight is sometimes a limiting factor in less developed areas. In all cases where this was a problem, there was not a corresponding armor threat. As such, in almost all cases, the missions and tasks of a tank can be fulfilled with other light armor (CFVs, IFVs, or APCs).
  3. The primary terrain problem is rivers and flooded areas. It would appear that in difficult terrain, especially heavily forested terrain (areas with lots of rainfall, like jungles), a robust river crossing capability is required.

Operational Factors

  1. Emergency insertions and delaying actions sometimes appear to be a good way to lose lots of armor for limited gain. This tends to come about due to terrain problems, enemy infiltration and bypassing, and the general confusion prevalent in such operations. The Army should be careful not to piecemeal assets when inserting valuable armor resources into a ‘hot’ situation. In many cases holding back and massing the armor for defense or counter-attack may be the better option.
  2. Transportability limitations have not been a major factor in the past for determining whether lighter or heavier armor were sent into a SSCO or a combat environment.

Casualty Sensitivity

  1. In a SSCO or insurgency, in most cases the weight and armor of the AFVs is not critical. As such, one would not expect any significant changes in losses regardless of the type of AFV used (MBT, medium-weight armor, or light armor). However, the perception that US forces are not equipped with the best-protected vehicle may cause some domestic political problems. The US government is very casualty sensitive during SSCOs. Furthermore, the current US main battle tank particularly impressive, and may help provide some additional intimidation in SSCOs.
  2. In any emergency insertion scenario or conventional war scenario, the use of lighter armor could result in higher US casualties and lesser combat effectiveness. This will certainly cause some domestic political problems and may impact army morale. However by the same token, light infantry forces, unsupported by easily deployable armor could present a worse situation.

U.S. Army Solicits Proposals For Mobile Protected Firepower (MPF) Light Tank

The U.S. Army recently announced that it will begin soliciting Requests for Proposal (RFP) in November to produce a new lightweight armored vehicle for its Mobile Protected Firepower (MPF) program. MPF is intended to field a company of vehicles for each Army Infantry Brigade Combat Team to provide them with “a long-range direct-fire capability for forcible entry and breaching operations.”

The Army also plans to field the new vehicle quickly. It is dispensing with the usual two-to-three year technology development phase, and will ask for delivery of the first sample vehicles by April 2018, one month after the RFP phase is scheduled to end. This will invariably favor proposals using existing off-the-shelf vehicle designs and “mature technology.”

The Army apparently will also accept RFPs with turret-mounted 105mm main guns, at least initially. According to previous MFP parameters, acceptable designs will eventually need to be able to accommodate 120mm guns.

I have observed in the past that the MPF is the result of the Army’s concerns that its light infantry may be deprived of direct fire support on anti-access/area denial (A2/AD) battlefields. Track-mounted, large caliber direct fire guns dedicated to infantry support are something of a doctrinal throwback to the assault guns of World War II, however.

There was a noted tendency during World War II to use anything on the battlefield that resembled a tank as a main battle tank, with unhappy results for the not-main battle tanks. As a consequence, assault guns, tank destroyers, and light tanks became evolutionary dead-ends in the development of post-World War II armored doctrine (the late M551 Sheridan, retired without replacement in 1996, notwithstanding). [For more on the historical background, see The Dupuy Institute, “The Historical Effectiveness of Lighter-Weight Armored Forces,” August 2001.]

The Army has been reluctant to refer to MPF as a light tank, but as David Dopp, the MPF Program Manager admitted, “I don’t want to say it’s a light tank, but it’s kind of like a light tank.” He went on to say that “It’s not going toe to toe with a tank…It’s for the infantry. It goes where the infantry goes — it breaks through bunkers, it works through targets that the infantry can’t get through.”

Major General David Bassett, program executive officer for the Army’s Ground Combat Systems concurred. It will be a tracked vehicle with substantial armor protection, Bassett said, “but certainly not what you’d see on a main battle tank.”

It will be interesting to see what the RFPs have to offer.

New U.S. Army Security Force Assistance Brigades Face Challenges

The shoulder sleeve insignia of the U.S. Army 1st Security Forces Assistance Brigade (SFAB). [U.S. Army]

The recent deaths of four U.S. Army Special Forces (ARSOF) operators in an apparent ambush in support of the Train and Assist mission in Niger appears to have reminded Congress of the enormous scope of ongoing Security Force Assistance (SFA) activities being conducted world-wide by the Defense Department. U.S. military forces deployed to 138 countries in 2016, the majority of which were by U.S. Special Operations Forces (SOF) conducting SFA activities. (While SFA deployments continue at a high tempo, the number of U.S. active-duty troops stationed overseas has fallen below 200,000 for the first time in 60 years, interestingly enough.)

SFA is the umbrella term for U.S. whole-of-government support provided to develop the capability and capacity of foreign security forces and institutions. SFA is intended to help defend host nations from external and internal threats, and encompasses foreign internal defense (FID), counterterrorism (CT), counterinsurgency (COIN), and stability operations.

Last year, the U.S. Army announced that it would revamp its contribution to SFA by creating a new type of unit, the Security Force Assistance Brigade (SFAB), and by establishing a Military Advisor Training Academy. The first of six projected SFABs is scheduled to stand up this month at Ft. Benning, Georgia.

Rick Montcalm has a nice piece up at the Modern War Institute describing the doctrinal and organizational challenges the Army faces in implementing the SFABs. The Army’s existing SFA structure features regionally-aligned Brigade Combat Teams (BCTs) providing combined training and partnered mission assistance for foreign conventional forces from the team to company level, while ARSOF focuses on partner-nation counterterrorism missions and advising and assisting commando and special operations-type forces.

Ideally, the SFABs would supplement and gradually replace most, but not all, of the regionally-aligned BCTs to allow them to focus on warfighting tasks. Concerns have arisen with the ARSOF community, however, that a dedicated SFAB force would encroach functionally on its mission and compete within the Army for trained personnel. The SFABs currently lack the intelligence capabilities necessary to successfully conduct the advisory mission in hostile environments. Although U.S. Army Chief of Staff General Mark Milley asserts that the SFABs are not Special Forces, properly preparing them for advise and assist roles would make them very similar to existing ARSOF.

Montcalm also points out that Army personnel policies complicate maintain the SFABs in the long-term. The Army has not created a specific military advisor career field and volunteering to serve in a SFAB could complicate the career progression of active duty personnel. Although the Army has taken steps to address this, the prospect of long repeat overseas tours and uncertain career prospects has forced the service to offer cash incentives and automatic promotions to bolster SFAB recruiting. As of August, the 1st SFAB needed 350 more soldiers to fully man the unit, which was scheduled to be operational in November.

SFA and the Army’s role in it will not decline anytime soon, so there is considerable pressure to make the SFAB concept successful. Yet, in light of the largely unsuccessful efforts to build effective security forces in Iraq and Afghanistan, it remains an open question if the SFAB’s themselves will be enough to remedy the Army’s problematic approach to building partner capacity.

U.S. Army Updates Draft Multi-Domain Battle Operating Concept

The U.S. Army Training and Doctrine Command has released a revised draft version of its Multi-Domain Battle operating concept, titled “Multi-Domain Battle: Evolution of Combined Arms for the 21st Century, 2025-2040.” Clearly a work in progress, the document is listed as version 1.0, dated October 2017, and as a draft and not for implementation. Sydney J. Freeberg, Jr. has an excellent run-down on the revision at Breaking Defense.

The update is the result of the initial round of work between the U.S. Army and U.S. Air Force to redefine the scope of the multi-domain battlespace for the Joint Force. More work will be needed to refine the concept, but it shows remarkable cooperation in forging a common warfighting perspective between services long-noted for their independent thinking.

On a related note, Albert Palazzo, an Australian defense thinker and one of the early contributors to the Multi-Domain Battle concept, has published the first of a series of articles at The Strategy Bridge offering constructive criticism of the U.S. military’s approach to defining the concept. Palazzo warns that the U.S. may be over-emphasizing countering potential Russian and Chinese capabilities in its efforts and not enough on the broad general implications of long-range fires with global reach.

What difference can it make if those designing Multi-Domain Battle are acting on possibly the wrong threat diagnosis? Designing a solution for a misdiagnosed problem can result in the inculcation of a way of war unsuited for the wars of the future. One is reminded of the French Army during the interwar period. No one can accuse the French of not thinking seriously about war during these years, but, in the doctrine of the methodical battle, they got it wrong and misread the opportunities presented by mechanisation. There were many factors contributing to France’s defeat, but at their core was a misinterpretation of the art of the possible and a singular focus on a particular way of war. Shaping Multi-Domain Battle for the wrong problem may see the United States similarly sow the seeds for a military disaster that is avoidable.

He suggests that it would be wise for U.S. doctrine writers to take a more considered look at potential implications before venturing too far ahead with specific solutions.
