USMC 76-96, in at 17 as a private, commissioned in 85, retired as a captain.
Started as a grunt (0341, mortarman, cross-trained as a machine gunner and platoon radio operator) - and nope, Der Adler, I'm not sorry, it was a great way to get to blow things up... at the time, every time I saw aircraft my first thought was, "shouldn't somebody be shooting at that?" Later gained a much greater appreciation, especially after getting to be friends with a USN CSAR 53 pilot (a great guy named Steve Edson, taught CSAR at MAWTS-1 in Yuma, a relative of the great Red Mike Edson of Guadalcanal renown.) I still liked ticking the airdales off by calling their flightsuits coveralls, though.
Did tours with 3rd Mar Div (Kilo Co, 3rdBn 4th Marines, Weapons Plt.), then 1st Mar Div (81mm mortar platoon, 3rd Bn 1st Marines), then got tired of being cold and wet and reenlisted for an MOS change to data systems. Stayed in data systems after I got commissioned 'cause I wanted a family life and already had a pretty bad back and a wrecked knee; they merged the MOS with the CommO MOS and I ended up spending a lot of time cold and wet anyway by the time I punched out.
I'd do it again in a heartbeat. I loved the life, the people, the USMC culture - it made me a much better person, taught me tons about people, and 95% of the time it was one of those "this doesn't feel like work - can't believe they pay me for this!" situations. It did probably cost me a couple of marriages, but they were mistakes anyway! Both my younger brothers followed me in, and it has made the three of us even closer than we would have been - my wife shakes her head sometimes and says we're talking in code again and asks us to switch back to English.
Anyway, that's my story and I'm sticking to it.
