Forgot to post last night again. Oops!

Starfleet Marines haven't been seen much in the shows (or at all? Though I think the MACOs of Star Trek: Enterprise qualify). But I like to imagine they havne't changed much. The motto "Retreat, Hell!" comes from the American 2nd Battalion of the 5th Marines ("Two Five") in World War I. Upon their arrival in the French trenches, a French officer advised a retreat, to which Lloyd responded: "Retreat? Hell, we just got here!"
