So I posted this back in the BF2 days and the thread consensus was that h4xxorrs were a much better play. Maybe we have a shot at it in Armed Assault.

The material below is as taught at the US Army Ranger School, excerpted directly from SH 21-76 United States Army Ranger Handbook (no copyright).

--[excerpt]--

Members of the breach/entry team should be numbered for identification, communication and control purposes.

1. The #1 man should always be the most experienced / mature member of the team, next to the team leader. The number one man is responsible for frontal and entry/breach point security.
   
2. The #2 man is directly behind the number one man in the order of movement and is normally responsible as an entry or clearing team member.
   
3. The #3 man is normally the team leader and is responsible for initiating all voice and physical commands. The team leader must exercise situational awareness at all times with respect to the task, friendly force, and enemy activity.
   
4. The #4 man is normally the automatic rifleman and is usually equipped with an M249 SAW. He is responsible for rear security and is normally the last man into the room and can respond with a tremendous amount of firepower, should the team leader require him to do so.

Entry point position and individual weapon positions are important. The clearing team members should stand as close to the entry point as possible, ready to enter.

Rooms are never entered with less than two men. The #1 or #2 man may shout "Short Room" if the room is too small for the whole team.

Team members must clear the point of entry to eliminate the enemy threat and allow remaining team members to move into the room. An entry point acts as a fatal funnel since it is the focal point for enemy weapon acquisition.

Team members move away from the entry point and assume positions within the room where the threat can best be eliminated. Any threat is eliminated or neutralized as individual team members move to their points of domination, not once you get there. Never move faster than you can accurately engage targets.

Four-Man Stack: The #1 man must act the quickest and make immediate decisions. The #1 man enters the room eliminating the immediate threat and has the option of moving left or right, moving to one of two corners. His ability to move to a corner will be determined by obstacles, size fo the room, and the enemy situation. As he enters through the entry point, he can visually check one of the corners and determine if there is an immediate threat. If there is a threat he moves to the threat, eliminating it as he moves to the corner. If no immediate threat exists in the first corner, he should consider "button-hooking" to the [next] corner to avoid being shot in the back.

The #2 man moves along the wall in the opposite direction of the #1 man. Both the #1 and #2 man clear the breach point, their immediate threat areas all while moving to their dominating corner of the room. The #3 man goes the opposite direction of the #2 man inside the room and at least one meter from the door. The #4 man moves in the opposite direction of the #3 man. All team members stop when they have cleared the door and have reached their point of domination within the room.

The #1 man enters and goes left or right based on immediate threat location. The #2 man goes the opposite direction of the #1 man and engages all targets of opportunity in his sector. These actions normally result in the room being "divided" in half and 100% of the room being scanned except for the upper levels. The #3 man enters, clears the fatal funnel to the left or the right, and primarly scans overhead areas. The #4 man enters and goes opposite the #3 man and continues to provide rear security as the situation dictates.

One practice the Rangers employ is breach capability. This would typically be the #3 or #4 man, who breaches the obstacle (blows the door, etc.) before the #1 and #2 men rush in. In ArmA I could see the #3 or #4 man using grenades, but then #1 better wait for them to go off before entering!

If anyone actually practices this post or shoot me an PM, I'd love to hear how it goes.

Boot.
