When I graduated from high school in '57, I was torn between the Coast Guard and the Army. I went with the Army because the recruiter said I could get schooling as a veterinary assistant - I was living on a ranch at the time.
I signed on the dotted line and off we went to the main recruiting inprocessing station in downtown LA. After endless tests, I was told there were no openings for vet assts but I could get training in repairing heavy construction equipment. So, I bit.
Long story short, from temporary parts clerk to retirement as an Admin NCO and PSNCO.
We lived in WWII barracks and drooled at all the goodies the Fly Boys had.
This is funny. A summer in high-school I was working construction and working with an Army vet. He had joined up to work in heavy equipment and ended up with heavy artillery which really didn't have the civilian future...
Anyways, I will say in my time, there's two places I found with the best food and barracks and such. Air force Bases, and Sub bases. Subs did that since with the rotations it's 6 months at sea in the smallest ship as far as food/living/entertainment quarters. So the 6 months back they make sure you are taken care of. For a qual, we had to know the average per person budget the military got for food. I forget the number, something like 3 dollars a day around 2000. And we always used to joke about wondering where the other 2 bucks went to. Sub bases... lol
In Iraq we'd always head to Balad air base rather than Anaconda when we were out there. Same in Kuwait with LSA vs. the Rock (can't think of their official names). We got kinda lucky though as we fell under different operational commands out there and got that choice. But I remember the Rock had a pool (australian compound dug their own but had to fill it in when some general flew over), much better DFAC, better gym, store, etc.
As for the ASVAB, I did well on that, kept getting asked if I wanted to go Nuke (nuclear MM) but didn't want the 6 year sign-up. Which I ended up taking anyways after my post A-school training for an adjustment to my job. Anyways it definitely didn't relate anything to a civilian job, but was exciting, and was able to wrap up my degree while in.
