Definitely agree that the age to serve in the military should be raised to 21.  So many teenagers signed up for the military after 9/11 seemingly on an impulse, without the maturity of knowing what they were getting into until it was too late. Military recruiters also target these younguns.  That's not to say everyone shouldn't complete a year of community service at age 18, but in their own community, not in an Asian or Middle Eastern community halfway around the world.
