i was issued a m-16 when i first got to vietnam, nov 67, worked ok for me, but i picked up a ak-47 from a young guy that wasn't going to need it any more ( tet 68). ( long story made short, he had 3 rounds in his pocket and the rifle was still full of cosmolene.) i quit carring the m-16 and carried the ak and an m-79 the rest of my tour. i kept the m-16 cleaned and ready just in case. nothing wrong with it, but i like the confusion it caused when they thought there own buddies were shooting at them. i was on a 9 man mobility team that operated a "operational landing" yep, an air force guy. a couple of pictures of our weapons. a couple pictures of captured weapons. firefight on the airfield. last one is me, early morning after all night time fire fight.
