The Army needs to learn from the Marine Corps some TT&P on how to employ their rotary wing assets and not get the crap shot out of them, as well as how to keep up with a highly mobile and fast moving ground component. I'll quote a major from my squadron who used to fly helos in the Army, "If you want to create screwed up tactics for a weapons system, give it to the Army."
The USMC, has a dedicated WTI program for its aviators, which demands tough realistic training and applies sufficient dollars to the flying hour program to ensure that the pilots can meet the demands of the environments. You won't see this in the Army (see former post), except for TF 160. The unwillingness of higher eschelon types to recognize that the number of aircraft in the force structure has little to do with the outcome is the root cause of the problem; numbers of well trained crews to fly those aircraft will always be the long pole in the tent. Once the Army gets its head from its ass and starts putting in the time and dollars, the Apache will be an excellent asset.
