Lanchester Models

This is only tenuously connected to the topics of fighting and warrior culture, but i came across the idea of Lanchester models a few days ago. Basically, these are mathematical models of attrition in combat. One of the interesting consequences of this particular model is that the size of the group involved in combat is more important than the skill of the individual fighters, which seems contrary to the special forces model that seems to be advocated for the fight against non-centralized guerrilla or terror groups. Of course, these are pretty simple models and they apply more to traditional combat engagements.
