"I'm Asking You Sergeant, Where's Mine?" by Billy Connolly?

This one is sort of in no man's land, if you'll pardon use of the term. As well as resentment of the misleading recruitment ploys used to hook him, the singer/soldier seems to imply condemnation of his own poor judgment in joining up (as contrasted with that of his wiser pacifist brother in Glagow who "Is nae [as] saft").

Songs lamenting the soldier as victim of the war machine are certainly easier to find than songs that actually single the soldier himself out and hold him personally responsible.

Interesting thread.
