Helicopters are there to support the troops on the ground while the Air Force is more fixed wing or "Fighter Mafia" type aircraft. There was an Army program called "high school to flight school" but with all the cuts it looks like this might be less likely than going Army ROTC so you can take your chances with it. As an aviation branched commissioned officer you won't always be flying but riding a desk for much of your career but as a warrant you should ALWAYS be flying. The Army is the only branch that has this option as far as I know the Marines, Navy and Air Force are smaller and more selective on picking up pilot candidates.

I was never in an aviation unit or a warrant/commissioned officer so I don't know that much about that but I looked into becoming an officer years ago and took the AFAST (Army Alternate Flight Aptitude Selection Test) and it was tough most of the material on the test can be studied for the following lonks may help good luck.
