The December 2018 issue of Phalanx, a periodical journal published by The Military Operations Research Society (MORS), contains an article by Jonathan K. Alt, Christopher Morey, and Larry Larimer, entitled “Perspectives on Combat Modeling.” (the article is paywalled, but limited public access is available via JSTOR).
Their article was written partly as a critical rebuttal to a TDI blog post originally published in April 2017, which discussed an issue of which the combat modeling and simulation community has long been aware but slow to address, known as the “Base of Sand” problem.
In short, because so little is empirically known about the real-world structures of combat processes and the interactions of these processes, modelers have been forced to rely on the judgement of subject matter experts (SMEs) to fill in the blanks. No one really knows if the blend of empirical data and SME judgement accurately represents combat because the modeling community has been reluctant to test its models against data on real world experience, a process known as validation.
TDI President Chris Lawrence subsequently published a series of blog posts responding to the specific comments and criticisms leveled by Alt, Morey, and Larimer.
How are combat models and simulations tested to see if they portray real-world combat accurately? Are they actually tested?
How can we know if combat simulations adhere to strict standards established by the DoD regarding validation? Perhaps the validation reports can be released for peer review.
Some claim that models of complex combat behavior cannot really be tested against real-world operational experience, but this has already been done. Several times.
If only the “physics-based aspects” of combat models are empirically tested, do those models reliably represent real-world combat with humans or only the interactions of weapons systems?
Is real-world historical operational combat experience useful only for demonstrating the capabilities of combat models, or is it something the models should be able to reliably replicate?
If a Subject Matter Expert (SME) can be substituted for a proper combat model validation effort, then could not a SME simply be substituted for the model? Should not all models be considered expert judgement quantified?
Persuading the military operations research community of the importance of research on real-world combat experience in modeling has been an uphill battle with a long history.

U.S. Army Major Amos Fox has published a very intriguing analysis in the Association of the U.S. Army’s Institute of Land Warfare Landpower Essay series, titled “The Reemergence of the Siege: An Assessment of Trends in Modern Land Warfare.” Building upon some of his previous work (here and here), Fox makes a case that sieges have again become a salient feature in modern warfare: “a brief survey of history illustrates that the siege is a defining feature of the late 20th and early 21st centuries; perhaps today is the siege’s golden era.”
Noting that neither U.S. Army nor joint doctrine currently addresses sieges, Fox adopts the dictionary definition: “A military blockade of a city or fortified place to compel it to surrender, or a persistent or serious attack.” He also draws a distinction between a siege and siege warfare; “siege warfare implies a way of battle, whereas a siege implies one tool of many in the kitbag of warfare.” [original emphasis]
He characterizes modern sieges thusly:
The contemporary siege is a blending of the traditional definition with concentric attacks. The modern siege is not necessarily characterized by a blockade, but more by an isolation of an adversary through encirclement while maintaining sufficient firepower against the besieged to ensure steady pressure. The modern siege can be terrain-focused, enemy-focused or a blending of the two, depending on the action of the besieged and the goal of the attacker. The goal of the siege is either to achieve a decision, whether politically or militarily, or to slowly destroy the besieged.
He cites the siege of Sarajevo (1992-1996) as the first example of the modern phenomenon. Other cases include Grozny (1999-2000); Aleppo, Ghouta, Kobani, Raqaa, and Deir Ezzor in Syria (2012 to 2018); Mosul (2016-2017); and Ilovaisk, Second Donetsk Airport, and Debal’tseve in the Ukraine (2014-present).
Fox notes that employing sieges carries significant risk. Most occur in urban areas. The restrictive nature of this terrain serves as a combat multiplier for inferior forces, allowing them to defend effectively against a much larger adversary. This can raise the potential military costs of conducting a siege beyond what an attacker is willing or able to afford.
Modern sieges also risk incurring significant political costs through collateral civilian deaths or infrastructure damage that could lead to a loss of international credibility or domestic support for governments that attempt them.
However, Fox identifies a powerful incentive that can override these disadvantages: when skillfully executed, a siege affords an opportunity for an attacker to contain and tie down defending forces, which can then be methodically destroyed. Despite the risks, he believes the apparent battlefield decisiveness of recent sieges means they will remain part of modern warfare.
Given modern sieges’ destructiveness and sharp impact on the populations on which they are waged, almost all actors (to include the United States) demonstrate a clear willingness—politically and militarily—to flatten cities and inflict massive suffering on besieged populations in order to capitalize on the opportunities associated with having their adversaries centralized.
Fox argues that sieges will be a primary tactic employed by proxy military forces, which are currently being used effectively by a variety of state actors in the Eastern Europe and the Middle East. “[A]s long as intermediaries are doing the majority of fighting and dying within a siege—or holding the line for the siege—it is a tactic that will continue to populate current and future battlefields.”

Many will also be watching to see if the SFAB concept validates the Army’s revamped approach to Security Force Assistance (SFA)—an umbrella term for whole-of-government support provided to develop the capability and capacity of foreign security forces and institutions. SFA has long been one of the U.S. government’s primary response to threats of insurgency and terrorism around the world, but its record of success is decidedly mixed.
Earlier this month, the 1st SFAB commander Colonel Scott Jackson reportedly briefed General Joseph Votel, who heads U.S. Central Command, that his unit had less than eight months of training and preparation, instead of an expected 12 months. His personnel had been rushed through the six-week Military Advisor Training Academy curriculum in only two weeks, and that the command suffered from personnel shortages. Votel reportedly passed these concerns to U.S. Army Chief of Staff General Mark Milley.
Competing Mission Priorities
Milley’s brainchild, the SFABs are intended to improve the Army’s ability to conduct SFA and to relieve line Brigade Combat Teams (BCTs) of responsibility for conducting it. Committing BCTs to SFA missions has been seen as both keeping them from more important conventional missions and inhibiting their readiness for high-intensity combat.
However, 1st SFAB may be caught out between two competing priorities: to adequately train Afghan forces and also to partner with and support them in combat operations. The SFABs are purposely optimized for training and advising, but they are not designed for conducting combat operations. They lack a BCT’s command, control and intelligence and combat assets. Some veteran military advisors have pointed out that BCTs are able to control battlespace and possess organic force protection, two capabilities the SFABs lack. While SFAB personnel will advise and accompany Afghan security forces in the field, they will not be able to support them in combat with them the way BCTs can. The Army will also have to deploy additional combat troops to provide sufficient force protection for 1st SFAB’s trainers.
Institutional Questions
The deviating requirements for training and combat advising may be the reason the Army appears to be providing the SFABs with capabilities that resemble those of Army Special Forces (ARSOF) personnel and units. ARSOF’s primary mission is to operate “by, with and through” indigenous forces. While Milley made clear in the past that the SFABs were not ARSOF, they do appear to include some deliberate similarities. While organized overall as a conventional BCT, the SFAB’s basic tactical teams include 12 personnel, like an ARSOF Operational Detachment A (ODA). Also like an ODA, the SFAB teams include intelligence and medical non-commissioned officers, and are also apparently being assigned dedicated personnel for calling in air and fire support (It is unclear from news reports if the SFAB teams include regular personnel trained in basic for call for fire techniques or if they are being given highly-skilled joint terminal attack controllers (JTACs).)
SFAB personnel have been selected using criteria used for ARSOF recruitment and Army Ranger physical fitness standards. They are being given foreign language training at the Military Advisor Training Academy at Fort Benning, Georgia.
The SFAB concept has drawn some skepticism from the ARSOF community, which sees the train, advise, and assist mission as belonging to it. There are concerns that SFABs will compete with ARSOF for qualified personnel and the Army has work to do to create a viable career path for dedicated military advisors. However, as Milley has explained, there are not nearly enough ARSOF personnel to effectively staff the Army’s SFA requirements, let alone meet the current demand for other ARSOF missions.
An Enduring Mission
Single-handedly rescuing a floundering 16-year, $70 billion effort to create an effective Afghan army as well as a national policy that suffers from basic strategic contradictions seems like a tall order for a brand-new, understaffed Army unit. At least one veteran military advisor has asserted that 1st SFAB is being “set up to fail.”
Yet, regardless of how well it performs, the SFA requirement will neither diminish nor go away. The basic logic behind the SFAB concept remains valid. It is possible that a problematic deployment could inhibit future recruiting, but it seems more likely that the SFABs and Army military advising will evolve as experience accumulates. SFA may or may not be a strategic “game changer” in Afghanistan, but as a former Army combat advisor stated, “It sounds low risk and not expensive, even when it is, [but] it’s not going away whether it succeeds or fails.”
