Being a military helicopter pilot is actually harder than a fixed wing pilot. I can hear the jet jockeys screaming now! The reason, is because you use all of your limbs to fly a chopper and you can fly backwards (which I am told is disorienting). The thing that stops most people from flight school is the physical. I had an applicant for Army flight school washed out because he had a hearing deficit at 3khz in his left ear. You might save yourself lots of time and ask your doctor if he/she knows what a military flight physical entails and could you pass it?
