as SecDef and he also did some harm. One of his problems was that he was a smart and successful guy -- that leads to the ego overwhelming common sense -- and the added fact that he was absolutely clueless about the Army; what it did and how it did it; about land warfare (and in 2003 had no knowledgeable land warfare adviser around; Myers sure didn't qualify...) and probably also had a mild Navy and aviator bias led him to make a lot of dumb mistakes about the Army.

There's nothing as cost-ineffective as a Rifle or a Tank Company in peacetime; Rumsfeld had the vision that the Army was still running thousands of troops around cutting grass and painting rocks as they had been when he was a young Flight Instructor -- he was never an operational aviator -- so he was checklist and metric happy...

I don't know if he was, as rumored, the one who insisted on trashing the TPFD but he obviously allowed it and that was one of many really dumb decisions on the way in.
