Coincidentally, I just helped a couple of AWs down in Pensacola with their warrant applications but provided the following guidance to fore warn them before they submitted their applications;
Before you commit yourself enter Army Aviation you have to understand there is a cultural difference that doesn't exist in any other service. Helicopter pilots are basically a mobility support asset the same as a tank, APC, truck, etc on the battle field. We know it's cooler, but the rest of the Army doesn't care. That said, the quality of life is vastly different than an aviator of the other sister services. Not worse, just different.
It is a true statement that if you want to fly, do not become a 2LT! It's not uncommon to find LTCs (C.O.s) commanding battalions with 500-600 hrs TT) The rank structure aside, you basically choose to branch off on a command track, rather than as a professional pilot. There are exceptions, but generally the CWOs are the unit IPs, Flight leads, etc
Lastly, I tell aspiring Army pilots if you desire to fly helicopters, the Army will absoultely fullfill their end of the bargain. Beyond getting winged, they make no further promises, so don't set yourself for dissapointment by expecting more. Also, your committment after winging is only 6 years, which leaves you young enough to pursue other options. I know many Army aviators that are now flying Hornets, B-1's, Harriers, etc for other services.
I've never had to spend much time in a regular Army unit. If Bobbyrock is lurking around here, he's usually got sound advice for junior birdmen that may be more accurate than mine.
Good Luck!
