If we had mandatory military service for all over 18yo, like Mexico and Israel for instance, people like you and the others who've served would have a much different experience with civilians.
My dad served, even though he's incredibly anti-government, so that he could finish his medical training (radiologist, was a flight surgeon in the Navy). Even with everything he has to say about the (civilian) government, he taught me, as did my grandparents and mother, that military people live a hard life between pay rates and, hell, even just getting through boot camp is a hell of an experience. But the people who are serving in combat or unfriendly zones, those people have an extra-super measure of respect and admiration from me. They're doing one of the hardest jobs in the world, if not THE hardest.
Hell, I can't even stick a needle in someone to give 'em a shot because I get the shakes so bad. Get a little bit too hot and I've got a headache that makes me puke. Then I read about what soldiers/servicepeople go through and I know that I AM A WEENIE.
