Haji the Afghanhound says:

If you are sitting in Afghanistan, on a former Soviet air base, waiting in your operations hut to recover the crew that went out to pick up casualties from an insurgent attack, and you want to put a movie in the DVD player to kill time while you wait for them to get back,

Don't pick Red Dawn.

(And I thought Blackhawk Down was a bad thing to watch out here...  )
