I thought the army gave up combat aircraft when the Army Air Corps became the Air Force in 1947 
@GtHawk That was before my time,but I THINK that was the first dust-up because the US Army and the former "Army Air Force".
MY generation dust-up was over the army having spotter airplanes and armed helicopters. The USAF didn't really give a squat about the helicopters because "helicopters ain't jets and they ain't sexy",but almost stroked out over spotter planes for ground troops.
In the end the Army was allowed to keep armed helicopters and the small "Cessna" type prop planes to use for jobs the USAF didn't want to be troubled with.
I don't think most people know this,but during the VN War the USAF had at least one squadron of "combat attack helicopters" based in Thailand that flew actual combat and combat rescue missions into Laos and Cambodia in support of US SF recon teams and Hatchet Force platoons. It was easy to tell they were USAF instead of US Army because they were painted blue.
I'd really like to see these guys get the recognition they deserve for the risks they took.
