Clear A Room:
1. Room clearing techniques are described using the standard four-man fire team. This does not mean that all four members must enter a room, nor does it mean that more than four men cannot enter. The fire team organization is the baseline from where units adapt to the specific situation. This is because the compartmentalized nature typical of buildings and rooms makes units larger than squads awkward and unmanageable.
2. For this battle drill to be effectively employed, each member of the team must know his sector of fire and how his sector overlaps and links with the sectors of the other team members. No movement should mask the fire of any of the other team members.
3. On the signal, the team enters through the entry point (or breach). As the team members move to their points of domination, they engage all threats or hostile targets in sequence in their sector. The direction each man moves should not be pre-planned unless the exact room layout is known. Each man should, however, go in a direction opposite the man in front of him (Figure 7-11). For example:
#1 Man. The #1 man enters the room and eliminates any immediate threat. He can move left or right, moving along the path of least resistance to a point of domination—one of the two corners and continues down the room to gain depth.
#2 Man. The #2 man enters almost simultaneously with the first and moves in the opposite direction, following the wall. The #2 man must clear the entry point, clear the immediate threat area, and move to his point of domination.
#3 Man. The #3 man simply moves in the opposite direction of the #2 man inside the room, moves at least 1 meter from the entry point, and takes a position that dominates his sector.
#4 Man. The #4 man moves in the opposite direction of the #3 man, clears the doorway by at least 1 meter, and moves to a position that dominates his sector.
4. Once the room is cleared, the team leader may order some team members to move deeper into the room overwatched by the other team members. The team leader must control this action. In addition to dominating the room, all team members are responsible for identifying possible loopholes and mouseholes in the ceiling, walls, and floor. Cleared rooms should be marked IAW unit SOP.
