Urban Operations

Buildings will always be encountered in arma, they provide solid defensive positions, and break up the country side refreshingly. However entering these areas can be extremely hazardous as you are now dealing with three dimensional combat. The enemy is no longer on a plane around you, they are up on rooftops, in ally wyas, hiding through windows. The following will cover how to manouver saftly through a built up area, and deal with occupied buildings.



We use formations in urban environments just as we do in open. These formations are moulded to the availability of cover around you. Principles of sector discipline, communication and fluidity are more important here than how you have been operating.



  • Shape your stance to your cover.
  • Do not cross in front of someone.
  • Leave a little room behind you for members to pass.
  • Worry about your own sector.
  • Weapons are always raised
  • Maintain Line of Sight with friendlies
  • If you are contacted, react with your basic drills, then move immediately to cover.
  • As a minimum always have a buddy.
  • Wall Stack

    A wall stack will give you 180 cover instantly, and is used when a lack of cover or movement options are given.

    Corner Stack

    Corner stack is used when you are holding at a corner of a wall or building. NOTE this is not used on every corner you approach, but only when you have reason to suspect danger, or have already been contacted.

    Corner Bound

    Notice when bounding, one member is always watching 90 in any direction. When you reach the corner, whoever is covering the gap hugs the wall, whilst his buddy leaves a space for members to pass between.
    If more security is needed on the opening, the second buddy can aim over the shoulder.


    buddy’s split onto either side of the road, covering the opposite team. When bounding, one man holds each corner, whilst the other two move.

    Structure clearing.


    So a hostile party has taken refuge in a building? No problems, lets talk about how to correctly storm the building.

    Think about the structure.

    How many floors does it have, where are the entries, what positions of the building will prevent you from gaining entry (enemy has a fire lane onto that area or inside the building towards your entry point). Have an idea of what your about to go into and have a plan to get the job done.

    Entry. Clear from the Outside in.

    Stacking up on doors primarily help with command and control, and assisting the fluidity of the breach. However once you have cleared a few buildings, the enemy knows your there and will try to fight you on your approach, causing entries to be more dynamic (team is already spaced as they approach the door, this allows the first guy to move across and get a quick idea before anything happens). When clearing a building, the safest way is to do so without ever entering. This is done by pieing windows and door ways for bad guys to remove as many blind spots as possible. If you have no time to clear all apertures, at the minimum do the point of entry.

    Clearing a Room

    Lets cover some things before we go on;



    Red Zone: An area that cannot be seen or cleared

    Priority of Work: Red Zones, Open doors/apertures, closed doors, locked doors.

    Fatal Funnel: An aperture that provides a fire lane, that also is used for movement between areas of the building (doors, destroyed walls etc)


    Pieing any room before entry is the smartest thing to do, albiet there is time (sometimes you may need to just secure it at the immediate point), ensure you pass on what you see to your team.

    eg “red zone right, open door right, obstruction furniture front, red zone left.”

    This enables your team an understanding of the environment they are about to enter and what their priorities are upon entering. Once it is checked from the door, the team can start preparing for the room.


    Depending on the threat, you may wish to have two members move together to pie the room, just ensure if you receive fire to keep moving to cover, don’t stop in the funnel

    If able to (you are secure outside the building and wont be damaged by the internal blast), it is a good idea to frag the room and pie again, this call should be made by the team leader and let everyone know what is going to happen…

    Whoever goes in first doesn’t matter, as long as they follow the path of least resistance, ie move as forward as possible into the first corner. From there the second man goes to the opposite corner and the team staggers their entry. The first two entering who are clearing the corners, clear from the corner to center of the room, and the second 2 that enter should be clearing center to corner. Once the team is in, start working on your priorities, ie clear red zones in the room and secure open apertures.
