David raises his hands, stepping further outside with the rest of them. He begins removing his gear, leaving only his uniform. He reaches underneath the coat, pulling out his identification, as well as unholstering his pistol before throwing it onto the ground.
As he's reaching underneath his uniform again to retrieve more gear, he repeatedly presses onto his radio. Though it's not a message of any sorts, it sends out a series of clicks to the nearest German outpost (which is most likely at the border of michigan), as a sort of panic-call or distress signal from their unit. David continues with pulling the radio out, dropping it onto the ground with the rest of his gear.
Nothing really that interesting can be found in the truck other than a couple rifles and ammunition.
"L-Look, we don't have anything against you guys, really!"
