Having started as an enlisted reservist I have to say that it’s a lot of fun that I wouldn’t trade for the world, but I was 18, single, no kids.
What everyone said above is on target. My advice would be to go back to PLC/OCC. As long as you didn’t get a bad write-up when you left, they’ll take you back.
They have a short program in flight school for certified pilots and with your experience you could probably do well enough to pick anything you want to fly. (Of course everyone knows the top of the class always picks CH-53Es... ain’t that right USMCFLYR)
