two iraqi guards, one chewing a slim jim, look bewildered as they stare at the circling infiniti fifty yards away. iraqi soldiers fire a grenade that blows up right behind the rolls as doc skids right up to a rear entrance of the bunker, the grill touching the metal door. doc parks, blockading the rear door shut, and, with three shiite riflemen, jumps out. imam, lying in a ditch, is concealed on the side of the bunker, and aims an old rifle at the chopper. archie, troy, doc, stunned -- turn back to the bunker. imam, from the side of the bunker, fires again, the chopper swivels toward him to return fire -- slow to freeze frame mid-stride -- with just the sound of the chopper: archie, doc, troy, three abreast, mid-stride.
