What made Vietnam vets different was that almost all of us went over alone
and came back alone. No units in/out for most people, You just showed up one day and one day you left. There was a tremendous sense of guilt when you got to go home and your buddies stayed. My big mindscrew was that I was drafted, selected for SF and OCS and refused both, I was sent to a signal battalion because I worked for the phone company when I was drafted. So not only did I get out of the Infantry, but some other poor guy took my slot at OCS and got himself shot up. It has bothered me for 40 years. It was the smart thing to do, but that doesn't help. I was in the 5th Inf Div when the OCS thing came up and sat next to a Captain who had just come back from the Ia Drang fight. He said "I'm going to give you the best piece of advice you will ever hear, Don't do this, if you do, you are going to be an Infantry platoon leader and you are going to get killed" I took his advice.
