A friend of mine in high school took the same path, he was a very bright guy. He did his 5 or 6 years took the GI bill, got an engineering degree and now works in aviation.
He told me that he went to "pole climbing school" and as dumb as it sounds he was one of only three that passed.
Pole Climbing,. I would rather do the obstacle course twice than climb a 40' pole..
My path was about the same as my son wants..
Washout rates are incredible sometimes, my kids mos right now is 0352 Missle launcher.
Maybe 20 other young men in his class, with the identify your target test, 4 or 5 failed out.
I think he told me it was 200 different targets they needed to identify. He told me with today's technology if they laz the wrong tank ( Russian or Danish? ) it will instantly lock in on them and send three rounds killing them. I think he said at advanced Missle School it's a few hundred more..
His roommate now was in his squad bay at New River, he's almost 30 yrs old, so they all call him pops. At chow he gets teased to drink milk so not to break his hip.
He's a smart guy it seems, no bad habits except for a Marine mouth..
They were buddy's during liberty at SOI and still hang together.
