The only reason I would join the army is to get away from problems and because it is a purposefull job I would be good at. I mean whatg other job allows you to do something meaningful that is challenging to the mind while allowing you to escape all the problems of civilian life. As John Knowels put it,
" To enlist. To slam the door impulsively on the past, to shed everything down to my last bit of clothing, to break from the pattern of my life-that complex design I had been weaving since birth with all its dark threads, its unexplainable symbols set a against a conventional background of domestic white and schoolboy blue, all those tangled strands that required the dexterity of a virtuoso(violin player?) to keep flowing-I yearned to take giant military scissors to it, snap! bitten off in an instant, and nothing left in my hand but spools of military khaki."
That's from A Seperate Peace, a suck-tastic novel I had to read for school.
Basically it sums up why I would enlist, to get away from the complex problems of life and replace it with the clear, simple problem of a person trying to kill you. Plus, I am pretty fit and am an ok commander/ soldier, judging from Rome Total War and Paintballing. (I've only been paintballing once, but I was pretty good at it, even though my damn gun broke.)
Another thing...Say I'm a Chinese guy who tries to join the PLA but for whatever reason can't make it. If I still wanted to fight for China (any China) coul dI go join the ROC military, or would I be rejected as a spy? I just thought that would be sort of funny.
