anecdotally, what I had seen was, that combat vets volunteered to go back into the soup because they couldn’t stand the mundane routine of everyday stateside military life.
Even in peacetime the move from 180m,ph to 75 mph is difficult - my lucky experience post gulf war... when its 400 to 75 i couldnt imagine.
As was said, sometimes it ends badly...
I made friends with a Cpl. @ 29 palms. He had already been to Vietnam and was wounded.
The Marines were giving early outs, based on MOS, to those who had already gone to Vietnam.
We were already playing defense by then (Nixon’s Vietnamization of the war)
My friend had 24 months or so left on his enlistment and decided it was worth another 13 months to get out 11 months early.
He said he didn’t feel “comfortable” stateside anyway.
He got there before I did and had kind of set the table for me - showed me the ropes. The country was on lockdown for the change in MPC (Military payment certificate. Basically, they changed colors on the bills, making the old ones worthless. It ruined the civilians)
We were going to Taiwan for our out-of-country R&R over the Christmas holidays.
We decided to take an in-country day R&R @ China Beach the Monday after t-giving.
We got there and went our separate ways.
I came back. He didn’t.
