I'd love to give an alturistic motive for joining, but it was just really a pretty selfish motive that prompted me to join. There was a sensei in my life who one once said that he didn't wan't to look in the mirror 40 years later and have the person looking back say "You shoulda, you coulda". I grew up building military models, watching military documentaries, playing strategy games, my dad was part of the occupation forces in Japan with the 11th Abn.. Add the fact that I wasn't doing well in a second attempt at college, so I joined. I joined to see if I could do it - not for patriotism nor to fight for my country. I talked the talk, so I decided to walk the walk. It was one enlistment with a line company in the 82nd Abn (peacetime). Closest to combat I got was taxiing down the runway to Haiti.
It was MY first life choice - college was just assumed by all. Glad I did it; glad it was over.
I decided to get out after the Pope Air Force Base (Green Ramp) Tragedy and when I got married. I didn't feel it was right to raise a family with the spectre of my never coming. So I got out.
Now, after that is answered, here's like a bonus question. Why do people join the army during wars? I'm sure they know that they might die, but SO many people join the army during wars, I'm sure. What's the point? Why not just stay a civilian, the army can handle itself, don't you think?
Thanks.

I won't speak for those who join during war, but looking back, as a single 21 year old, I probably still would have joined. The physical nature in me probably would have still put in the infantry, but I'd give more thought to the airborne forward observer slot they offered me. Those choppers looked good while I was slogging through the mud at oh-dark-thrity.
And to the very last question:
1) the obvious answer revolves around apathy depleting the force, but
2) there's a second answer about the military being able to handle itself, power currupting, answering to a civilian governmen, or protecting a constitution. Great for debates, but probably too close to some mines for this forum...I'll let someone else lay the engineers tape for that one..
