i have NG two friends that have/are putting in multiple tours. they get excited about the adventure, neither was psyched about the second tour, but they're going (well one is there), neither is active combat, but rather supporting. the honeymoon is really quick for them and they're ready to come home. the pay is (if single) enhanced by the fact that you can't spend to much of it over there I guess (well lose it at poker I guess?).
my friend currently there has diverse (& divorced) parents:
1. a dad who is a super right wing gun nut
2. a mom is a super liberal social worker
If you want to meet a "moderate", i have met no one who matches the description more than him.
