  • The "Official" Room Clearing Thread w/ pics

    There are numerous techniques for close combat engagement based in our doctrine, but basic infantry tactical success essentially depends on one thing: Battle Drills. Our doctrine has evolved over time, but our battle drills have not; Battle Drill 6 - Enter Building/Clear Room is one case in point. Based on my experience as a Rifle Company Commander in Somalia and FM 7-8, Battle Drill 6 is a dangerous, ineffective and an outdated method of clearing a room for any type of military operation.

    FM 7-8 describes the basic room-clearing technique by first positioning a clearing team on either side of the room entrance. Once the team is in position, the lead man "cooks off" a hand grenade and throws it into the room. Following the explosion, the lead man enters the room by engaging all "identified or likely enemy positions with rapid, short bursts of automatic fire and scans the room. The rest of the team provides immediate security outside the room." Following the initial entry, the lead man is responsible for positioning the other members of the team as he calls them into the room with the command "NEXT MAN IN, LEFT (RIGHT)". Based on the enemy situation, this battle drill can be done with two men entering the room at the same time from opposite sides of the entrance. Both men enter the room simultaneously with one high and one low to prevent fratricide.

    Understanding the basic layout of a room is critical to understanding this proposed drill. Based on experience in Somalia, over 95 percent of all engagements inside a building were within 25 feet. Additionally, the entrance to a room is where the enemy expected us to enter and is, therefore, the most vulnerable and critical point (decisive point).

    Figure 1 shows a basic room with this decisive point or Fatal Funnel. We also identified four "Points of Domination" (PDO) and a direction of fire ("No Man's Land") using the four corners of the room. The side of the room entrance that the clearing team enters from determines the location of "No Man's Land" (Figure 1). The key to this battle drill is to mass the maximum amount of fire power possible at the fatal funnel and quickly move through it to your assigned POD orienting all weapons toward No Man's Land. Each man has one mission: secure your POD. Any perceived threat along the route to each POD is engaged. Fragmentation grenades should only be used on heavy resistance and stun grenades are preferred due to less obscuration and fratricide potential. Either fragmentation or stun grenades should be used sparingly to avoid establishing a pattern for the enemy to detect when a room will be entered.

    The "Stack" or positioning of personnel outside the room is vital in getting firepower quickly through the fatal funnel. What POD for which each soldier is responsible is based on the position he is in the stack. Unlike the current Battle Drill 6, this drill does not attempt to synchronize and push two men with equipment through a doorway at once, or send one man in to fight a room alone. The physical contact of the men as they flood into the room provides the synchronization and confidence needed.


    Figure 1

    Knowing the responsibilities of each position in the stack is essential in actual combat situations. The casualties, fatigue, security and confusion associated with actual combat makes maintaining even platoon integrity difficult. It was not uncommon for soldiers from different platoons to be tasked to clear a room or series of rooms. Knowing all the positions of the stack made this possible.

    Figure 2 describes the responsibilities for each man in the stack. Regardless of what side of the entrance the stack enters, the duty of each man remains the same. The two primary positions, 1-Man and 2-Man, are responsible for the left and right limit PODs. Depending on which way the door opens, one of these men must ride the door all the way to the wall to ensure it is clear. The 1-Man always moves across the doorway and goes to the deep corner of the room (straight and long). The 2-Man always buttonhooks the doorway and moves to the near corner (buttonhook and short). The 3-Man and 4-Man follow the 1-Man and 2-Man respectively and establish their PODs. Additionally, these men must complete their lead man's mission in the event he is wounded or has a weapon malfunction (signaled by taking a knee). The 4-man has the additional duty of placing the door charge in the event the door is blocked.


    Figure 2

    While it is possible to conduct this battle drill with only three men, using four men is the preferred technique. Four men clearing a room gives the flexibility to a team required in the event there are additional, unknown rooms, or casualties. In Somalia, rooms were typically cluttered and extremely difficult to move around. The fourth man assisted greatly. In actual combat, the probability of success decreases greatly after three men and only under the most extreme circumstances should two men attempt to clear a room. One man should never attempt to clear a room alone.

    Figures 3 and 4 illustrate this battle drill using four or three men:






    All soldiers in the stack must understand several key points when executing this battle drill. Massing combat power at and through the fatal funnel does not equate to running through the doorway. Movements by the members of the team must be deliberate and synchronized with each other. This is why physical contact between members of the team is critical. Each man stacks up outside the entrance as tight as he can with the man to his front. Weapons are pointed down with the exception of the 1-Man who provides front security. Once the 4-Man is ready to move into the room, he pushes his knee into the 3-Man to signal he is ready. The 3-Man does the same to the 2-Man and 2-Man the same to the 1-Man. Once the 1-Man feels the tap of the 2-Man, he moves into the room quickly focusing on his route to his POD. Any threat he sees that prevents him from getting to his POD is engaged with two rounds using the basic quick-fire technique from FM 23-9. Developing this tunnel vision as well as trusting yourself, your buddy and your equipment is essential for success in this battle drill.

    Here is a simple walk thru:

          I love it and would love even more if we could take the time to work on this with a few players. Maybe we could use the 13th practice server if possible since it's password protected. Any thought's on that?

            I am waiting on the TGU inststuctors to give me the go ahead and then I will work it thru P.Drona for the server specifics.

            As soon as thats all complete I will post up the information.

            Thanks very much for your interest!!

            I am soooo looking forward to executing this in game since I have done it so many times real world.

              It won't work. Every single guy coming through the door is going to be killed if you follow this drill. It works great in real-life, but in a videogame nobody gives a crap about being killed and will calmly sit there and plink away at the fatal funnel as each guy glides into the doorway at the exact same speed and height.

                We practiced the 4 man stack last night. The key is to flashbang and frag the room first then move through the funnel. It's not foolproof but it worked more times than not.

                  As Drona pointed out, it does work if done properly.

                  We walked the dog on this one and found that the FB and stuns do what they are intended to do; however, if the bad guy in the room hears the clink clink of the FB or stun he knows to face the door and spray as he is blind and if he is locked on the door shooting he will wipe out anyone coming into the fatal funnel.

                  But if your team follows with a frag grenade a second later the threat will be weakened by the FB/Stun and when the grenade goes off your guaranteed a kill.

                  Even recorded a video for proof so check it when possible.

                    So essentially is it the frag through the door that kills the occupants?

                      Yes.

                      But considering if you were to throw a Stun you would get a hit indicator identifying a threat in the room and thus the grenade would remove the threat.

                      The other take away on this strategy is that the threat is looking at the door. Once the FB or stun goes off the threat is now aware there are people attempting to get into the room and will remained aimed at the door. The frag then goes in while the player is blinded and is killed. If the FB and Stun dont go into the room then then the threat will see the grenade come into the room and either run out or look for cover thus nullifying the grenade and placing the rest of the team back into the fatal funnel.

                        The advantages of using this out weighs the negatives.

                        I think that in real game play, it should work very well. A player covering a doorway has distractions, lack of patience, and other combat variables playing into the situation.

                        Yes, there is the possibility that a defender can still cover the door despite a stun and frag being thrown... but you have to admit the breaching team has significantly reduced the threat to themselves with this tactic.

                        Without the tactic, I'd give the breaching team about a 5% chance of success without major casualty. With the tactic, I'd think the chances are well over 80%. I'll take that any day.

                        And if you think about it, it is not just the tactic alone which adds to this. It is the organized and trainable manner in which a team can operate. If you can practice it, you can become better at it. If you get really good, and know how you're going to approach it, you've already given yourself a huge edge.

                            I would really like to see that added to the lineup.

                            Then we would really be on par with the CS:S mates.

                              I hate to be the second Nay sayer of this. But gillespie is right. I have been on competitive teams on the TWL ladder and in several other ladders and to say that this tactic doesnt work in video games is dead on. The reason for this is:
                              1. While FBs do work, kinda, if the red cell is pointed at the door as they are supposed to all they have to do is spray and pray. You will knock out the first if not the second and third guy.

                              2. This tactic is best used if the enemy doesnt know your coming. In video games, we know your coming. We may not know exactly when, but we dont have to wait for hours, just a few minutes.

                              3. Its an ambush with the red side holding the advantage. They only need 2 or 3 people in the room to have the destinct advantage on you. They are the ones holding the cover and they are the ones expecting you to enter. Its the rule of 3 when an ambush is involved. 1 ambusher will likely take out 3 ambushees. Or conversely, it takes 3 in a patrol to typically overrun each person on an ambush team.

                              Thats not to say its not worth trying out. Its fun to work with and a great team building exercise. But practically speaking, it will fail more times than not.
