Odd Nobel Awards

nobel_prize

It is really hard to find a more distinguished award than the Nobel awards, created by Alfed Nobel, the Swedish “merchant of death” that invented dynamite and owned Bofors. But there have been a few prizes awarded that are a little odd to say the least. Earlier this month they awarded the Nobel peace prize to Juan Manuel Santos, for negotiating a peace agreement to end the 52 year war between the government of Colombia and the rebel group Fuerza Armadas Revolucionarias de Colombia (FARC). But five days before the announcement of the prize, the peace deal was rejected by a referendum of Colombian voters. So, peace prize awarded, but no peace.

Just in case the Colombian War has not been on your horizon, not only is it the longest running hot conflict in the world, but it has resulted in the deaths of over 200,000 people. This makes it the second bloodiest war ever in the Western Hemisphere, behind the U.S. Civil War (1861-65) and ahead of the Chaco War (1932-1935).

The war has always operated at a fairly low level. The bloodiest year for the counterinsurgency forces was in 2002 with 1,207 deaths and an estimated 1,817 insurgent deaths. By 2005 these figures had dropped to 143 and 63 respectively. The peak U.S. involvement was in 2002 with 224 advisors. These figures are drawn from our Dupuy Insurgency Spread Sheets (DISS). We never assembled a total figure of deaths from the war so cannot confirm the often used figure of over 200,000 killed, but starting in 1988, the number of homicides in Colombia exceed 20,000 a year, and they were less than 10,000 a year only five years earlier. The war peaked in 2002 and is much, much quieter now.

There have been other strange prizes awarded over the years, like President Obama getting awarded one in 2009, when all he had done to date was get elected nine months earlier. There was a prize awarded in 1973 to Henry Kissinger and Le Duc Tho for the Paris agreement that brought a ceasefire in the Vietnam War. Le Duc Tho refused to accept the award. The war continued for another two years after the prize, culminating with North Vietnam overrunning South Vietnam. Certainly it was peace at that point, but hardly in the spirit of the prize.

There is one Nobel prize awarded recently that was not odd, this was the literature prize for Bob Dylan. About time! There is no question that Bob Dylan was the single most influential lyricist (and therefore poet) in world in the last 50 years. Before Bob Dylan, song lyrics were basically “she loves you, yea, yea, yea.” After Dylan, there wasn’t a whole lot of subjects not being addressed. Dylan came from a rich American folk and blues tradition very much developed by Woody Guthrie, Leadbelly and Pete Seeger. He embraced it, enhanced it, and left an indelible mark on popular music. Just as Homer originally recited his poetic narratives to music, many modern poets are singers and songwriters. This prize just recognizes that obvious, but sometimes overlooked point. People don’t read or write a lot of poetry these days, but they do listen to a lot of music and lyrics. These lyrics are often bad poetry, but not all of them. Some published authors and poets have become song writers (Leonard Cohen and Rod McKuen come to mind, for example). They did not cease to be poets when they became song writers. Even the name of this blog is drawn from a “popular song,” just to drive home the point. Modern poetry often includes a backbeat, be it NWA or Bob Dylan.

Last verse:

Yes, my guard stood hard when abstract threats

Too noble to neglect

Deceived me into thinking

I had something to protect

Good and bad, I define these terms

Quite clear, no doubt, somehow

Ah, but I was so much older then

I’m younger than that now

Kursk Book Availability

Kursk

Amazon.com is now charging $275 for my Kursk book. For some reason, they had always discounted it to below list price. Last week, the discounted ended and it now cost well above list price. We have no say in what Amazon.com does or does not do. We have watched the odd price fluctuations on the book prices there with considerable bemusement.

It is available from Aberdeen Bookstore at the list price of $195. If you click on the image of the book to the right of this post then it will lead you there.

Lanchester equations have been weighed….

a-knights-tale_1

There have been a number of tests of Lanchester equations to historical data over the years. Versions of Lanchester equations were implemented in various ground combat models in the late 1960s and early 1970s without any rigorous testing. As John Stockfish of RAND stated in 1975 in his report: Models, Data, and War: A Critique of the Study of Conventional Forces:

However Lanchester is presently esteemed for his ‘combat model,’ and specifically his ‘N-square law’ of combat, which is nothing more than a mathematical formulation of the age-old military principal of force concentration. That there is no clear empirical verification of this law, or that Lanchester’s model or present versions of it may in fact be incapable of verification, have not detracted from this source of his luster.”

Since John Stockfish’s report in 1975 the tests of Lanchester have included:

(1) Janice B. Fain, “The Lanchester Equations and Historical Warfare: An Analysis of Sixty World War II Land Engagements.” Combat Data Subscription Service (HERO, Arlington, VA, Spring 1977);

(2) D. S. Hartley and R. L. Helmbold, “Validating Lanchester’s Square Law and Other Attrition Models,” in Warfare Modeling, J. Bracken, M. Kress, and R. E. Rosenthal, ed., (New York: John Wiley & Sons, 1995) and originally published in 1993;

(3) Jerome Bracken, “Lanchester Models of the Ardennes Campaign in Warfare Modeling (John Wiley & sons, Danvers, MA, 1995);

(4) R. D. Fricker, “Attrition Models of the Ardennes Campaign,” Naval Research Logistics, vol. 45, no. 1, January 1997;

(5) S. C. Clemens, “The Application of Lanchester Models to the Battle of Kursk” (unpublished manuscript, May 1997);

(6) 1LT Turker Turkes, Turkish Army, “Fitting Lanchester and Other Equations to the Battle of Kursk Data,” Dissertation for MS in Operations Research, March 2000;

(7) Captain John Dinges, U.S. Army, “Exploring the Validation of Lanchester Equations for the Battle of Kursk,” MS in Operations Research, June 2001;

(8) Tom Lucas and Turker Turkes, “Fitting Lanchester Equations to the Battles of Kursk and Ardennes,” Naval Research Logistics, 51, February 2004, pp. 95-116;

(9) Thomas W. Lucas and John A. Dinges, “The Effect of Battle Circumstances on Fitting Lanchester Equations to the Battle of Kursk,” forthcoming in Military Operations Research.

In all cases, it was from different data sets developed by us, with eight of the tests conducted completely independently of us and without our knowledge.

In all cases, they could not establish a Lanchester square law and really could not establish the Lanchester linear law. That is nine separate and independent tests in a row with basically no result. Furthermore, there has never been a test to historical data (meaning real-world combat data) that establishes Lanchester does apply to ground combat. This is added to the fact that Lanchester himself did not think it should. It does not get any clearer than that.

As Morse & Kimball stated in 1951 in Methods of Operations Research

Occasionally, however, it is useful to insert these constants into differential equations, to see what would happen in the long run if conditions were to remain the same, as far as the constants go. These differential equations, in order to be soluble, will have to represent extremely simplified forms of warfare; and therefore their range of applicability will be small.

And later they state:

Indeed an important problem in operations research for any type of warfare is the investigation, both theoretical and statistical, as to how nearly Lanchester’s laws apply.

I think this has now been done for land warfare, at last. Therefore, I conclude: Lanchester equations have been weighed, they have been measured, and they have been found wanting.

Really…..Lanchester?

RAND described the combat system from their hex boardgame as such:

The general game design was similar to that of traditional board wargames, with a hex grid governing movement superimposed on a map. Tactical Pilotage Charts (1:500,000 scale) were used, overlaid with 10-km hexes, as seen in Figure A.1. Land forces were represented at the battalion level and air units as squadrons; movement and combat were governed and adjudicated using rules and combat-result tables that incorporated both traditional gaming principles (e.g., Lanchester exchange rates) and the results of offline modeling….”

Now this catches my attention. Switching from a “series of tubes” to a hexagon boardgame brings back memories, but it is understandable. On the other hand, it is pretty widely known that no one has been able to make Lanchester equations work when tested to historical ground combat. There have been multiple efforts conducted to test this, mostly using the Ardennes and Kursk databases that we developed. In particular, Jerome Braken published his results in Modeling Warfare and Dr. Thomas Lucas out at Naval Post-Graduate School has conducted multiple tests to try to do the same thing. They all point to the same conclusion, which is that Lanchester equations do not really work for ground combat. They might work for air, but it is hard to tell from the RAND write-up whether they restricted the use of “Lanchester exchange rates” to only air combat. I could make the point by referencing many of these studies but this would be a long post. The issue is briefly discussed in Chapter Eighteen of my upcoming book War by Numbers and is discussed in depth in the TDI report “Casualty Estimation Methodologies Study.” Instead I will leave it to Frederick Lanchester himself, writing in 1914, to summarize the problem:

We have already seen that the N-square law applies broadly, if imperfectly, to military operations. On land, however, there sometimes exist special conditions and a multitude of factors extraneous to the hypothesis, whereby its operations may be suspended or masked.
