This reads like an ad for the QJM model. The DePuy Institute had a proprietary model for figuring out who wins a battle. This was invented by General William DePuy, one of the leading planners of the US loss in Vietnam. He came up with a Quantitative Judgement Model for evaluating military strength. It's mostly adding up weapons values (sword = 1.0), although there are other features of the model. There are tables, now used mostly by war gamers. DePuy looked at a large number of historical battles, and came up with weights which seemed to work. The result was supposedly that the side with a 2:1 advantage almost always won. Within the 2:1 range, it was a tossup.

Two different people with differently spelled last names: General William DePuy (who was MACV C-o-S, BigRedOne-Six and then ran TRADOC after the war, and is considered the architect of the rebuilding of the Army after Vietnam) is unrelated to Col. Trevor Dupuy. Both of them fought in the US Army in WW2, and have confusingly similar names, but Dupuy is the one who founded the Dupuy Institute to do his numerical analysis of combat with all of his models and fudge factors.

Oh! Thanks.
