[The Comedian]

The punishment for stabbing a Marine in the back should be to submit the perp to the will of the other Marines for 30 seconds.

That would be about the extreme end of the scale for life expectancy.

Frowning takes 68 muscles.
Smiling takes 6.
Pulling this trigger takes 2.
I'm lazy.

[PAR35]

Armed combatant, not in uniform. He should be sent to Gitmo for the duration.
