The Army can't operate fixed wing attack aircraft. The Air Force got that restriction when they were created as a separate branch.
The Army had more pilots than the Air Force and the Navy in Viet Nam. I looked for pictures and came up with this, there were4 others like the armed Bronco and a small twin jet engined GS model. I don’t know how to post the pictures but here is a reference. I flew in a couple of the ARMY fixed wing aircraft, but not the ones with weapon racks.
air force is unconstitutional....fold them back into the ARMY
