I was Drama 05 in the year 1969 and we FAC'd for the 199th Light Infantry Brigade. AO was west of Sai Gon and east of Bien Hoa. I know that Drama/199th were together from around 1967 through sometime in 1970. Flew O-1's and traded up to the OV-10 in late 1968. OV-10 tail number 14626 was assigned to Drama's when it came in country and is the Bronco at the FAC memorial in the Air Park at Hurlburt AFB.
