Well, the Oh-6 DID have a smoke launcher, so it could mark targets for the cobra in Hunter-Killer (Pink) teams. It also had a minigun (well, some did). BTW i saw over at ofp-zone.com that they have info about the nam pack. Pretty impressive, but nothing about the ARVN (Army of the Republic of Vietnam - Southern Forces). I *believe* there were more ARVN casualties than US casualties in the war. Please correct me, I may be wrong, but in the Air Cav US and ARVN troops worked together occasionaly + on the ground.
