"They're in this warehouse. he said. "It used to be for soda, but now there's just guns and cash and stuff." David knew the one he was talking about. No ships ever went by the place except at night. He took a thin wad of twenties out of his jacket, and tossed it to him, even though this guys was probably too scared of him to tip anyone off that he was coming.
The next night, "The Army" was walking up to the warehouse. He didn't have any time for subtlety. The gang sure didn't. Maybe waking up one night and having your world destroyed would teach them a lesson. He stopped upside of the old warehouse, and made some backup. All three Davids kicked open the door, and threw smoke bombs strategically to cover the most space. Two took out machine guns, and one a shot gun, and held their fire for a moment, treasuring the gangsters' surprise.
