Two men swung a portable ram, smashing the rear door of the rowhouse right out of the frame. As the door went down, a third trooper flung a stun and smoke grenade that went off with a bang. Squad One rushed into the kitchen, weapons tracking from side to side, then called "clear" and moved on. Another grenade banged from the front of the house. Skip followed Squad One through the swirling smoke as far as the stairs to the basement and there pointed Squad Two up the hall toward the front of the house.
