Salute!
Yeah, Wolf, less time to fly in the Army aviation route. The biggie is the "dead end", and USAF has the best oppo, then USN or USMC. But if helos are your goal, it is likely better to go USMC than USN.
USAF offers more helos and fixed wing platforms and missions than the other services.
So go look up the stuff on the various websites of the military services.
Gums sends...
