Outside of the National Training Center in California, the Army hasn't really practice large scale force on force maneuvers since the 80's. That was why the 1st Gulf war was largely successful, although one could argue it took them forever and a day to amass the required forces, materiel and supplies. Since the 1st Gulf war, nearly 26 years ago, the Army is DRASTICALLY different. It is smaller. It has mostly the same old equipment, MAYBE with some technology upgrades. The soldiers of today have not experienced anything on this scale unless they are a very senior General and a veteran of the Gulf war as a very very junior officer of NCO. And now with the LBGTs who knows how macho the Army can be.
