War By Numbers Published

Christopher A. Lawrence, War by Numbers Understanding Conventional Combat (Lincoln, NE: Potomac Books, 2017) 390 pages, $39.95

War by Numbers assesses the nature of conventional warfare through the analysis of historical combat. Christopher A. Lawrence (President and Executive Director of The Dupuy Institute) establishes what we know about conventional combat and why we know it. By demonstrating the impact a variety of factors have on combat he moves such analysis beyond the work of Carl von Clausewitz and into modern data and interpretation.

Using vast data sets, Lawrence examines force ratios, the human factor in case studies from World War II and beyond, the combat value of superior situational awareness, and the effects of dispersion, among other elements. Lawrence challenges existing interpretations of conventional warfare and shows how such combat should be conducted in the future, simultaneously broadening our understanding of what it means to fight wars by the numbers.

The book is available in paperback directly from Potomac Books and in paperback and Kindle from Amazon.

15 Books Received !!!

I just received my 15 author copies of War by Numbers. So it is now available for $39.95 from Potomac Books (University of Nebraska Press): War by Numbers

This means it should be available from Amazon.com next week: War by Numbers

I don’t how quickly the foreign book sellers will receive them, but expect them to have  copies available in the next couple of weeks.

I did not order 200 copies for The Dupuy Institute to sell, unlike I did with America’s Modern Wars, so it will not be directly available from us: http://www.dupuyinstitute.org/booksfs.htm

This figure is on page 175 of the book, Chapter 14: Advance Rates:

 

 

Battle of Mosul Ends

Looks the Battle for Mosul had ended as of Sunday. A timeline is here: https://www.yahoo.com/news/iraq-battle-mosul-135450223.html

This thing took forever. The offensive started on 17 October. They entered the city on 1 November. It then took 251 days to take the city (over 8 months). This is one of the interesting challenges of urban warfare, it takes 15 days to get to the city and 251 days to take it. As we noted in our three urban warfare studies (and in two chapters in War by Numbers), operations outside of the urban area go so much faster than in the urban areas. The end result is that most urban warfare eventually turns into a giant mop-up operation.

I notice there has been a renewed interest in urban warfare, especially with discussions of fighting in mega-cities. I am not sure that everyone involved in these efforts grasp that these fights are not occurring at the point of the spearhead, but are indeed often a mop-up operation, regardless of the size of the city.

Mosul is in ruins. It is certainly one of the largest cities that ever had an extended urban fight in it. It is larger than Stalingrad.

So…does anyone have some good casualty figures for this fight?

Aussie OR

Over the years I have run across a number of Australian Operations Research and Historical Analysis efforts. Overall, I have been impressed with what I have seen. Below is one of their papers written by Nigel Perry. He is not otherwise known to me. It is dated December 2011: Applications of Historical Analyses in Combat Modeling

It does address the value of Lanchester equations in force-on-force combat models, which in my mind is already a settled argument (see: Lanchester Equations Have Been Weighed). His is the latest argument that I gather reinforces this point.

The author of this paper references the work of Robert Helmbold and Dean Hartley (see page 14). He does favorably reference the work of Trevor Dupuy but does not seem to be completely aware of the extent or full nature of it (pages 14, 16, 17, 24 and 53). He does not seem to aware that the work of Helmbold and Hartley was both built from a database that was created by Trevor Dupuy’s companies HERO & DMSI. Without Dupuy, Helmbold and Hartley would not have had data to work from.

Specifically, Helmbold was using the Chase database, which was programmed by the government from the original paper version provided by Dupuy. I think it consisted of 597-599 battles (working from memory here). It also included a number of coding errors when they programmed it and did not include the battle narratives. Hartley had Oakridge National Laboratories purchase a computerized copy from Dupuy of what was now called the Land Warfare Data Base (LWDB). It consisted of 603 or 605 engagements (and did not have the coding errors but still did not include the narratives). As such, they both worked from almost the same databases.

Dr. Perrty does take a copy of Hartley’s  database and expands it to create more engagements. He says he expanded it from 750 battles (except the database we sold to Harley had 603 or 605 cases) to around 1600. It was estimated in the 1980s by Curt Johnson (Director and VP of HERO) to take three man-days to create a battle. If this estimate is valid (actually I think it is low), then to get to 1600 engagements the Australian researchers either invested something like 10 man-years of research, or relied heavily on secondary sources without any systematic research, or only partly developed each engagement (for example, only who won and lost). I suspect the latter.

Dr. Perry shows on page 25:

Data-segment……..Start…….End……Number of……Attacker…….Defender

Epoch…………………Year…….Year……..Battles………Victories……Victories

Korea………………..1950…….1950…………..20……………….20………………0

Post WWII………….1950……..2008…………118……………….86…………….32

 

We, of course, did something very similar. We took the Land Warfare Data Base (the 605 engagement version), expanded in considerably with WWII and post-WWII data, proofed and revised a number of engagements using more primarily source data, divided it into levels of combat (army-level, division-level, battalion-level, company-level) and conducted analysis with the 1280 or so engagements we had. This was a much more powerful and better organized tool. We also looked at winner and loser, but used the 605 engagement version (as we did the analysis in 1996). An example of this, from pages 16 and 17 of my manuscript for War by Numbers shows:

Attacker Won:

 

                        Force Ratio                Force Ratio    Percent Attack Wins:

                        Greater than or         less than          Force Ratio Greater Than

                        equal to 1-to-1            1-to1                or equal to 1-to-1

1600-1699        16                              18                         47%

1700-1799        25                              16                         61%

1800-1899        47                              17                         73%

1900-1920        69                              13                         84%

1937-1945      104                                8                         93%

1967-1973        17                              17                         50%

Total               278                              89                         76%

 

Defender Won:

 

                        Force Ratio                Force Ratio    Percent Defense Wins:

                        Greater than or         less than          Force Ratio Greater Than

                        equal to 1-to-1            1-to1                or equal to 1-to-1

1600-1699           7                                6                       54%

1700-1799         11                              13                       46%

1800-1899         38                              20                       66%

1900-1920         30                              13                       70%

1937-1945         33                              10                       77%

1967-1973         11                                5                       69%

Total                130                              67                       66%

 

Anyhow, from there (pages 26-59) the report heads into an extended discussion of the analysis done by Helmbold and Hartley (which I am not that enamored with). My book heads in a different direction: War by Numbers III (Table of Contents)

 

 

Battle Outcomes: Casualty Rates As a Measure of Defeat

This third article in the box I was about to trash was also written by someone I knew, Robert McQuie. It was a five-page article published in Army magazine in November 1987 (pages 30-34) called “Battle Outcomes: Casualty Rates As a Measure of Defeat.” I was an article I was aware of, but had not seen for probably around three decades. It was based upon data assembled by HERO (Trevor Dupuy). It was part of the lead-in to the Breakpoints Project that we later did.

The by-line of the article is “A study of data from mid-twentieth century warfare suggest that casualties–whether the reality or the perception of them—are only occasionally a factor in command decisions to break off unsuccessful battles.” 

The analysis was based upon 80 engagements from 1941-1982. Of those 52 were used to create the table below (from page 34):

Reasons for a Force Abandoning An Attack or Defense:

Maneuver by Enemy…………………………..Percent

  Envelopment, encirclement, penetration……..33

  Adjacent friendly unit withdrew………………..13

  Enemy occupied key terrain…………………….6

  Enemy achieved surprise……………………….8

  Enemy reinforced………………………………..4

Total………………………………………………64

 

Firepower by Enemy

  Casualty or equipment losses……………………10

  Heavy artillery or air attacks by enemy…………..2

Total…………………………………………………12

 

Other Reasons

  No reserves left……………………………………….12

  Supply shortage………………………………………..2

  Truce or surrender…………………………………….6

  Change in weather…………………………………….2

  Orders to withdraw…………………………………….2

Total…………………………………………………….24

 

He then goes on in the article to question the utility of Lanchester equations, ending with the statement “It appears as well that Mr. Lanchester’s equations present a drastic misstatement of what drives the outcome of combat.” He also points out that many wargames and simulations terminate simulated battles at 15% to 30% casualties a day, ending with the statement that “The evidence indicated that in most cases, a force has quit when its casualties reached less than ten percent per battle. In most battles, moreover, defeat has not been caused by casualties.”

Robert McQuie was a senior operations research analyst for U.S. Army’s CAA (Concepts Analysis Agency). In 1987 I was working at HERO and considering heading back to school to get a graduate degree in Operations Research (OR). At Trevor Dupuy’s recommendation, I discussed it with Robert McQuie, who stated strongly not to do so because it was a “waste of time.” His argument was that while Operations Research was good at answering questions where the results could be optimized, it was incapable of answering the bigger questions. He basically felt the discipline had reached a dead end.

Anyhow, another keeper.

 

War by Numbers Page Proofs

Well, I do have the page proofs for War by Numbers, which I must absolutely get back to the publisher next week. It turns out the book is 374 pages. The Potomac Books/University of Nebraska Press site was saying 498 pages, which kind of mystified me as my Word final draft was only 342 pages. They also claim the book has 218 tables, 1 chart and 49 graphs, which sounds about right.

So looks like we are on track (barely) for an August release date.

Anyhow, probably should be busy reviewing and editing instead of writing blog posts.

Back to the Future

The opening sentence of an article by Dan Goure caught my attention: “Every decade of so since the 1960s, the U.S. Army creates a requirement for what can nominally be described as a light tank.” The article is here: http://nationalinterest.org/blog/the-buzz/its-back-the-future-mobile-protected-firepower-20539?page=show

It reminds me of a meeting we had in late 2000 with Walt Hollis, Deputy Under Secretary of the Army (Operations Research). He started the meeting by telling us that something like “Every now and then, someone seems to want to bring back the light tank.” He then went on to explain that these requirements are being pushed from the top (meaning by the Chief of Staff of the Army) and they should probably have a study done on the subject. He then asked us to do such an effort.

We did and it is here: http://www.dupuyinstitute.org/pdf/mwa-2lightarmor.pdf

We decided to examine the effectiveness of lighter-weight armor based upon real-world experience in six possible scenarios:

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

Anyhow, I am not going to summarize the report here as that would take too long. I did draft up a chapter on it for inclusion in War by Numbers, but decided to leave it out as it did not fit into the “theory testing” theme of the book. Instead, I am holding it for one of my next books, Future American Wars.

The interesting aspect of the report is that we were at a meeting in 2001 at an Army OR outfit that was reviewing our report, and they told us that the main point of action they drew from the report was that we needed to make sure our armor vehicles were better protected against mines. As our report looked at the type of tank losses being suffered in the insurgencies and OOTWs, there were a lot of vehicles being lost to mines. Apparently they had not fully realized this (and Iraq did not occur until 2003).

Economics of Warfare 14

Well, I managed to turn Dr. Spagat’s last lecture into three blog posts. Probably could do that for most of them. There is a lot in them. Moving onto the fourteenth lecture from Professor Michael Spagat’s Economics of Warfare course that he gives at Royal Holloway University. It is posted on his blog Wars, Numbers and Human Losses at: https://mikespagat.wordpress.com/

This lecture focuses on the impact of foreign aid on a conflict and starts with a study by Nunn and Qian (link to it is on slide 1). It is another cross-national study (by the way, I love cross-national studies). As always, Dr. Spagat’s asides are loaded with meaning. In this case, on slide 2 he again mentions the problem of reverse causation, where the subject you are trying to measure (the dependent variable) is in fact, probably influencing the so-called independent variable. In effect, you are trying to establish cause-and-effect when there is also a flow the other way (the effect is affecting the cause).

Moving through to slide 14 is the rather counterintuitive conclusion of the study done by Nunn and Qian which is that “US food aid seems to contribute to prolonging conflicts but not to starting new ones.” Not sure what to make of that.

He then shifts to a study that focuses just on the Philippines using an approach called the “regression discontinuity approach” (which is something I have never played with). What gets my attention is that the paper’s author’s (Crost, Felter and Johnston)  set up a way to do a side-by-side experiment looking at different municipalities that received aid vice ones that did not. As Dr. Spagat notes on slide 16: “Once again, the idea is to create a situation that resembles a controlled experiment.”

This “controlled experiment” or “side-by-side approach” was the basis of our three urban warfare studies done for the Center for Army Analysis and our situational awareness study that we did for OSD Net Assessment. In the first we looked at engagement results in urban areas vice non-urban areas; and in the situational awareness study we compared engagement results for situations where they knew a lot about their enemy compared to those where they did not. Both of these studies are discussed in some depth in my upcoming book War by Numbers, which I still think will be released this August.

The discussion after that gets a little dense, but the conclusion presented on slide 26 is that also that “…aid leads to conflict.” and “…that insurgents work specifically to prevent aid flowing so that they can prevent local governments from winning over its citizens by providing them with good services.” Interesting. We really have not done any comparable work on this.

Starting on slide 27, he looks are an analytical paper examining the issue rape during Civil War. Again, this is not something we have examined, but the paper is available through a link on slide 27 and discussed by Dr. Spagat in slides 27-34.

Anyhow, I could have easily broken this discussion into three or even four blog posts….but did not this time. Probably more useful than reading my blog post is to actually read Dr. Spagat’s lecture. The link to the lecture is here: http://personal.rhul.ac.uk/uhte/014/Economics%20of%20Warfare/Lecture%2014.pdf

The Iraqi Army Has Entered the Old City

The offensive is continuing and they have entered the old city: Iraq-forces-seize-ground-mosul-old-city

The estimate is that there are about 2,000 ISIL fighters left behind in Mosul (along with 700,000 civilians): in-mosul-a-heavy-but-not-crushing-blow-to-is-group

In Fallujah in 2004, they left behind about a 1,000 fighters. The November 2004 Fallujah operation did turn into a slow mop-up that cost the U.S. Army and U.S. Marines 65 KIA, 582 WIA, 1 NBD (non-battle death) and 54 NBI (non-battle injury).

Right now, I am editing Chapter 16 of my book War by Numbers. That chapter is called “Urban Legends” and covers the findings from the three reports we did on urban warfare in 2002-2004. So, if I have not been posting much lately on the blog, there is a good reason for it. Trying to keep the book on its scheduled August release date.
