Interested. [@Jaredthefox92]If you have any questions about this period in American history, please ask. Late in the war, US soldiers were wearing subdued patches, the M203 Grenade Launcher had replaced the iconic M79 and the US Army Rifle squad had reduced in size from 11 men to 9. The USMC rifle squad had reduced in size from 16 to 13. The Automatic Rifleman carried an M16A1 rifle with a bipod and extra ammo; firing on full auto all the time. You cannot say drug use was exactly rampant because in those units where esprit d'corp and strong leadership were available, drug use was non-existent. I know the US media likes to portray all americans serving in Southeast Asia as being drug users, but that is simply not true. This may have been true in REMF units, but not as much in front line combat units. REMF = Rear Echelon Mother Fuckers or POG = Personnel Other than Grunts.
