**(Would you believe, many flown by non-commissioned officers? Disgusting.)**
Are you sure?
I think you are confusing helicopters with UAVs.
Most Army Helicopters are flown by Warrant Officers.
A Warrant Officer is not a commissioned officer. Neither is he an enlisted man. They are "neither flesh,nor fowl, nor good red meat." Manny chopper jocks are warrant officers. The USAF and the NAVY believe that in order to operate a flying machine, one ought to be commissioned, i.e., "an officer and a gentleman."
