I can't pull this up at work, but if it's the one with the three or four terrorists in the farmer's field with a tractor and a couple of trucks, it's Apache video from a while back. There is, however, a video floating around out there from several years ago, in Afghanistan I believe, of an AC-130 tearing the hell out of a suspected terrorist safe house.
And yes, a salvo of depleted-uranium 30mm chaingun rounds from an Apache would ruin somebody's day, rather effectively. I don't know how far the helicopter was from the targets--probably pretty far if the terrorists couldn't hear it--but the accuracy of those bursts of fire is amazing.

Don't think those were DU rounds, rather HE, High Explosive. Much better against soft targets. They will definitely do a number on exposed "troops".
