Why are freaks, losers, and turd burglars attracted to military service?

Have there always been this many?

Living in a military town, it seems half the "vets" I meet any more aren't fit to mow a fuggin' lawn or cogent enough to vote.

You'd think these folks would avoid military service, but apparently not.
