Mainly the M9 Beretta 9mm, but a Sig 9mm is also issued to some.
And that is just absurd. If the guy wanted to get rid of evidence, don't you think he'd have destroyed the tape, too? Dollars to donuts, it was one of those staged propaganda films made by Syria or in Saddam's Iraq. I saw one too, where an oddly enough all Arab "American" squad (in all manner of uniform, none of it being correct however) beat and sexually assaulted this pair of Iraqi women, while they filmed it for some crazy reason, oh yeah, I know why, because it wasn't real. Neither one of these tapes stands up to any amount of scrutiny or even basic logic.
