Synopsis:  A guy is trained to kill, and when the war is over, society doesn’t want him back.  Sound familiar?

Memory Alpha Summary: Good morning, Vietnam

Review:  As far as Star Trek goes, this is fairly well done allegory about we treat our veterans.  It’s a bit hard to believe that this society was able to create a soldier so perfect that it can overtake an entire starship, but the role is played well by McCarthy and the show’s moral is well realized without hitting you over the head with it.
