AOR / AREA
OF RESPONSIBILITY
An
important aspect of room combat is the use of areas of responsibility, or
individual
AORs.
By dividing a room into pie like sections, the room can be cleared far
faster than when all operators try to cover all areas at the same time.
If there are 2 operators in the room they each have 50% of the room. But if
space allows and there are 4 operators the only have 25% of the room each.

Some
teams use the technique of predesignating which way each man will move after
entering a room. For example. First man takes left, the second right, or
vice a versa.
When using a doorway as the point of entry, the path of least resistance is
determined initially based on the way the door opens; if the door opens
inward he plans to move away from the hinges. If the door opens outward, he
plans to move toward the hinged side. Upon entering, the size of the room,
enemy situation, and furniture or other obstacles that hinder or channel
movement become factors that influence the number 1 man's direction of
movement. The point of using this technique is to get the first man into the
room as quickly as possible to allow him to clear the fatal funnel quickly
and allow the rest of the team to make a smoother entry rather than keep
them bogged up at the fatal funnel.
Another
method is to allow the first man to pick his direction based on immediate
threat. The partner then takes the opposite side of the room. This can only
be done once the assault has been initiated.
The only time a shooter will cross shoot into his partner's sector, is when
that shooter has cleared his side of the AO and is needed to support the
other shooter. A shooter may also cross shoot when his partner's primary
weapon malfunctions in the face of imminent danger.
