I was a Marine for 4 years, from 1971 to 1975. I was an avionics technician which was a “critical MOS”, meaning it’s hard to find people who are thusly trainable. After basic training and 9 months of electronics schools, my usual work was in an air-conditioned trailer with an armed guard constantly patrolling outside.
I could’ve collected a large bonus and a promotion for reenlisting, but I was not tempted. It would’ve been inevitable that I’d have to spend another year in Iwakuni, Japan, which was one of only 3 possible duty stations for people in my highly specialized job.
Imagine living in a building which was a prison prior to the U.S. occupation, in a 36 by 36 foot room with 23 other guys. The country is too expensive to do much besides stay on or around the base and get drunk during off-hours. There is a crematorium upwind and a nasty smell in the air almost constantly, with human ashes falling. To make life even worse, I was farmed out to the supply department to be the liaison between supply and avionics. I never had to work with a worse group of slackers and morons before or since.
If I had it to do over again I’d join the Air Force, which has far & away the better food and living quarters.
When I was in, pay was slightly better in other Services because the USMC didn’t give members a “uniform allowance” to pay for replacement uniforms (the initial issue in boot camp is free) and cleaning/pressing). If we wanted dress blues, we had to pay for them ourselves.
BTW, I never used an illegal drug before I was in electronics school in Millington, Tennessee.
