Non-Reg Multiple Rooms
Moving from room to room is difficult and dangerous when you are operating alone. Because you can only look and fire in one direction at a time, there is no perfect technique that eliminates all risk and covers all danger areas. If all doors are closed doors, moving from room to room is less difficult, since the sound of an opening door will give you time to pivot and orient your weapon towards the threat. You can treat each room as a separate problem, opening doors in sequence and using the various clearing techniques described so far to make your way through the entire house or building.
Open doors present a more difficult problem. You must quickly analyze the layout of the room so that you are able to clear one room while moving into position to conduct a sweep of the next room. Take advantage of cover and concealment in the room while moving and be prepared to fall back if necessary. Multiple open doors in one room present one of the most dangerous challenges for single-person clearing. However, with practice, you can learn to quickly clear multiple doorways, danger areas and rooms using a combination of the various techniques described so far. In some cases, your best option may be to use speed to your advantage and move to a better fighting position as quickly as possible. The quick clear technique is useful when you need to clear multiple open doors.
For single-person operations, it is even more difficult to apply fixed rules or formulas to solve tactical problems, particularly when clearing multiple rooms. Situational awareness will be extremely important. Keep your “head on a swivel” and remain alert for any signs of the adversary. Listen for movement. Watch for shadows moving across the floor. Stop momentarily behind a covered and concealed position if necessary to improve your listening ability. Move cautiously and minimize your exposure.
