Nancy & Lee have a song called 'Congratulations' about an emotionally scarred war veteran who "won't finish that treehouse he started/ The month before he went away." It's hook is "Congratulations. You sure made a man out of him." A great anti-war song if ever there was one, and it chokes me every time I hear it.
10,000 Maniacs' 'Gun Shy' hits out at the military posturing too. Like this one, too.
