My college education was paid for by the GI Bill. No problems whatsoever. The training I got set me up in a career field that pays more than average for people of my age.
Was I ever worried about getting killed? Hell, yes! I joined up during Vietnam. During my time we had many other fights: Grenada, Panama, GulfWar I, etc. My last tour of duty I spent time sitting on my flak jacket as we flew over Bosnia, in case people on the ground decided to shoot at us.
If I had the choice to do it all again, would I? In a heartbeat!
