Figure A-35. Clearing a Room (Continued) g. Another option for entering a room (situation dependent): If Shooter Number One of the clearing team enters a room without Shooter Number Two immediately following him/her (this could be due to room size, entering the room through a narrow opening, or a number of factors caused by the situation), then Shooter Number One will position himself/herself inside the room to the left or right of the door and quickly scan the entire room. He/She then gives the command to Shooter Number Two, “NEXT MAN IN, LEFT (RIGHT).” Shooter Number Two shouts, “COMING IN, LEFT (RIGHT),” enters the room, positions himself/herself up against the wall to the left (right) of the entrance as designated, and scans the room. Once in position, the clearing team leader can call in additional members with the “NEXT MAN IN” command, as the situation dictates. It is critical that all assault element members tell each other where they are to avoid fratricide. h. When the clearing team has cleared the room and is ready to exit the room, it uses the following voice alerts. Once a room has been cleared, the clearing team yells, “CLEAR,” to inform the covering team. Before leaving the room and rejoining the covering team, the clearing team yells, “COMING OUT” and waits to hear the covering team yell, “ALL CLEAR.” The clearing team then executes its movement out of the room. The assault element then marks the room according to unit SOP. When moving up or down a staircase, the appropriate team yells, “COMING UP” or “COMING DOWN.” As before, it waits for the response “ALL CLEAR” before executing movement and rejoining its element. When exiting a building, the clearing team or assault element yells, “COMING OUT” and waits for the support force or covering team to respond with “ALL CLEAR.” 20. Clearing a Room, Door Closed, Split Positions a. Before opening a door, Shooter Number Two of the clearing team positions himself/herself opposite Shooter Number One on the other side of the door and away from the wall in a safe position that allows Shooter Number One to shoot the door-opening mechanism (Figure A-36). This positioning allows Shooter Number Two to be in position to immediately move to a wall position opposite Shooter Number One.
