You were the first guy to enter the hallway b with your Glock in the bSulb position. As you entered the hallway b had you seen anyone b you would have made a bheartbeatb decision as to whether or not they posed a threat. The odds are b they wouldnbt pose a threat b and at that time you would yell bBuilding Security b please return to your rooms immediately!b
You would be providing sole frontal security at this time. Only a second or two behind you would be your other two team-mates. (Remember the fourth team member is hustling the families to your location and are just 10-20 seconds behind you.)
As your team mates enter b they take up their security positions.
It would look like this:
Your sectors of fire would look like this:
Notice that the whole hallway is covered. The team can move like this with relative security b but hallways are dangerous places to move b as EVERY door, window, coke machine, table, air-conditioning vent, etc. b is a danger area. You MUST think in terms of a 360 degree hostile environment. Ceilings, walls, floors, front and back. Continuously scan these areas within your Sector of Fire.
You pretty much wait by the front door b covering the hallway b until the whole group is there b then you will assemble into the 4 man hallway security formation. It looks like this: (Be advised that the women and children are in between the 3 man group and the 4th man.
Sectors of fire:
You will be continuously communicating to your team-mates band they to you. bMovingb bClosed door rightb bCoke machine leftb etc. ANYONE can stop or halt the movement by saying bStopb b then communicating why.
If you are searching for bad-guys - movement will be slow and deliberate b a few feet per second is a good rule of thumb. However b in this instance you are just looking for a bsafe roomb and can move quicker.
In a btextbookb building clearing you NEVER pass by a door that you havenbt cleared that room. However b in this case b you are not searching for bad guys b you are searching for a safe place to hide out. So b you wonbt be taking the time clear the whole dang building. You will pick a room b and then clear it.
You are obviously wanting to pick a room that allows good security b and a 2nd way out b and one that provides good avenues of fire b should that become necessary. I would avoid 2nd floor (or higher) rooms b as riots tend to burn buildings down b and it would be bpoor formb to be stuck on the 2nd story of a building when it is on fire. Although b from a security standpoint the first floor is the LEAST secure. As always there are trade-offs and compromises to be made. The choice is yours and your team-mates. Go with what you feel is best for the given situation b and adapt and overcome obstacles when they present themselves.
Once you locate what you think would be a bgood roomb b the three of you would bstackb outside the door b and the fourth man would provide rear security.
