The weaponry makes me think they were Army Military Police.
NO...They were ''APs''.. Air Police in US Air Force uniforms..
''AP'' arm bands.. ONLY relation to US Army was to their training.
All APs and MPs were trained in the same location.. At that time
US Military Police School was located @ Ft Gordon Ga.. Now its
Ft Rucker Alabama... After Viet Nam in 1972 l was assigned to
Ft Gordon Ga... While there we did quite a bit of work for the
MP School.. The plastic shop at Training Aids made quite a few
rubber S&W revolvers and 1911 Colts... Smiths were RB 4'' K
frame M&Ps...
