Ken's cite is the book.....there is also a video you can get with Fox narrating it. It is a must read. he talks about combat modelling, what soldiers will generally do in combat, etc.(bunching, not keeping intervals, (the reason for non-coms!) how a unit enters a fight with a set emotional psyche, disintergration from within rather than from outside etc.) He applies the modelling to the historical record, narrative and archealogical record. Believe it or not, after the burn, he was able to trace actual indian firing positions and movement based upon cartridge signatures on the casings discovered as well as trooper positions, by evidence of rounds found coming in at impact points and cartridge cases where troopers fired from fixed positions. It is really fascinating.
