CQB Tactics
3-21. CONSIDERATIONS FOR ENTRY
The entire team enters the room as quickly and smoothly as possible and clears the doorway immediately. If possible, the team moves from a covered or concealed position already in their entry order. Ideally, the team arrives and passes through the entry point without having to stop.
a. The door is the focal point of anyone in the room. It is known as the fatal funnel, because it focuses attention at the precise point where the individual team members are the most vulnerable. Moving into the room quickly reduces the chance anyone being hit by enemy fire directed at the doorway.
b. On the signal to go, the clearing team moves from covered or concealed positions through the door quickly and takes up positions inside the room that allow it to completely dominate the room and eliminate the threat. Team members stop movement only after they have cleared the door and reached their designated point of domination. The first man's position is deep into the near corner of the room. The depth of his movement is determined by the size of the room, any obstacles in the room, such as furniture, and by the number and location of enemy and noncombatants in the room.
c. To make precision room clearing techniques work, each member of the team must know his sector of fire and how his sector overlaps and links with the sectors of the other team members. Team members do not move to the point of domination and then engage their targets. They engage targets as they move to their designated point. However, engagements must not slow movement to their points of domination. Team members may shoot from as short a range as 1 to 2 inches. They engage the most immediate enemy threats first. Examples of immediate threats are enemy personnel who—
· Are armed and prepared to return fire immediately.
· Block movement to the position of domination.
· Are within arm's reach of a clearing team member.
· Are within 3 to 5 feet of the breach point.
d. Each clearing team member has a designated sector of fire unique to him initially and expands to overlap sectors of the other team members.
(1) The number 1 and number 2 men are initially concerned with the area directly to their front, then along the wall on either side of the door or entry point. This area is in their path of movement, and it is their primary sector of fire. Their alternate sector of fire is from the wall they are moving toward, back to the opposite far corner.
(2) The number 3 and number 4 men start at the center of the wall opposite their point of entry and clear to the left if moving toward the left, or to the right if moving toward the right. They stop short of their respective team member (either the number 1 man or the number 2 man).
e. The team members move toward their points of domination, engaging all targets in their sector. Team members must exercise fire control and discriminate between hostile and noncombatant room occupants. Shooting is done without stopping, using reflexive shooting techniques. Because the soldiers are moving and shooting at the same time, they must move using careful hurry. (Figure 3-31 in paragraph 3-23, shows all four team members at their points of domination and their overlapping sectors of fire.)
3-22. TECHNIQUES FOR ENTERING BUILDINGS AND CLEARING ROOMS
Battle Drill 6 is the standard technique used by the four-man fire team when they perform the task, Enter Building/Clear Room. However, ROE may not allow for, nor the enemy situation requires, such aggressive action on the part of the assaulting unit. Based on the aforementioned conditions, commanders may determine to use the following techniques when entering and clearing buildings and rooms.
a. Situation. Operating as part of a larger force (during daylight or darkness), the squad is tasked to participate in clearing a building. The platoon leader directs the squad to enter the building or to clear a room. An entry point breach has already been identified, or will be created before initiating the entry.
b. Special Considerations. Platoon and squad leaders must consider the task and purpose they have been given and the method they are to use to achieve the desired results.
(1) To seize or gain control of a building may not always require committing troops into the structure or closing with the enemy. The following steps describe effective techniques to be used when training soldiers to the toughest possible conditions. These techniques and procedures can be trained, rehearsed, and modified to a specific situation and mission. Before initiating this action the employment of all organic, crew-served, and supporting weapon systems should be directed onto the objective area in order to suppress and neutralize the threat, providing the mission and ROE permit.
(2) When conducting urban operations, soldiers must be equipped at all times with a night vision device or light source to illuminate the immediate area.
NOTE: The following discussion assumes that only the platoon's organic weapons are to support the infantry squad. Urban situations may require precise application of firepower. This situation is especially true of an urban environment where the enemy is mixed with noncombatants. Noncombatants may be found in the room, which can restrict the use of fires and reduce the combat power available to a squad leader. His squad may have to operate with no fire areas. Rules of engagement can prohibit the use of certain weapons until a specific hostile action takes place. All soldiers must be aware of the ROE. Leaders must include the specific use of weapons in their planning for precision operations in urban terrain.
c. Required Actions. Figures 3-27, 3-28, 3-29, and 3-30 illustrate the required actions for performing this task.
(1) The squad leader designates the assault team and identifies the location of the entry point for them.
(2) The squad leader positions the follow-on assault team to provide overwatch and supporting fires for the initial assault team.
(3) Assault team members move as close to the entry point as possible, using available cover and concealment.
(a) If an explosive breach or a ballistic breach is to be performed by a supporting element, the assault team remains in a covered position until the breach is made. They may provide overwatch and fire support for the breaching element if necessary.
(b) All team members must signal one another that they are ready before the team moves to the entry point.
(c) Team members avoid the use of verbal signals, which may alert the enemy and remove the element of surprise.
(d) Assault team members must move quickly from the covered position to the entry point, minimizing the time they are exposed to enemy fire.
(4) The assault team enters through the breach. Unless a grenade is being thrown prior to entry, the team should avoid stopping outside the point of entry.
(a) The number 2 man may throw a grenade of some type (fragmentation, concussion, stun) into the room before entry.
(b) The use of grenades should be consistent with the ROE and building structure. The grenade should be cooked off before being thrown, if applicable to the type of grenade used.
(c) If stealth is not a factor, the thrower should sound off with a verbal indication that a grenade of some type is being thrown ("frag out," "concussion out," "stun out"). If stealth is a factor, only visual signals are given as the grenade is thrown.
|
CAUTION If walls and floors are thin, fragments from fragmentation grenades and debris created by concussion grenades can injure soldiers outside the room. If the structure has been stressed by previous explosive engagements, the use of these grenades could cause it to collapse. Leaders must determine the effectiveness of these types of grenades compared to possibilities of harm to friendly troops. |
(5) On the signal to go, or immediately after the grenade detonates, the assault team moves through the entry point (Figure 3-27) and quickly takes up positions inside the room that allow it to completely dominate the room and eliminate the threat (Figure 3-30). Unless restricted or impeded, team members stop movement only after they have cleared the door and reached their designated point of domination. In addition to dominating the room, all team members are responsible for identifying possible loopholes and mouseholes in the ceiling, walls and floor.
NOTE: Where enemy forces may be concentrated and the presence of noncombatants is highly unlikely, the assault team can precede their entry by throwing a fragmentation or concussion grenade (structure dependent) into the room, followed by bursts of automatic small-arms fire by the number one man as he enters.
(a) The first man (rifleman), enters the room and eliminates the immediate threat. He has the option of going left or right, normally moving along the path of least resistance to one of two corners. 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.
(b) The direction each man moves in should not be preplanned unless the exact room layout is known. Each man should go in a direction opposite the man in front of him (Figure 3-27). Every team member must know the sectors and duties of each position.
(c) As the first man goes through the entry point, he can usually see into the far corner of the room. He eliminates any immediate threat and continues to move along the wall if possible and to the first corner, where he assumes a position of domination facing into the room.

Figure 3-27. First man enters a room.
(6) The second man (team leader), entering almost simultaneously with the first, moves in the opposite direction, following the wall and staying out of the center (Figure 3-28). The second man must clear the entry point, clear the immediate threat area, clear his corner, and move to a dominating position on his side of the room.

Figure 3-28. Second man enters a room.
(7) The third man (grenadier) simply goes opposite of the second man inside the room at least one meter from the entry point and moves to a position that dominates his sector (Figure 3-29).

Figure 3-29. Third man enters a room.
NOTE: If the path of least resistance takes the first man to the left, then all points of domination are the mirror image of those shown in the diagrams.
(8) Points of domination should not be in front of doors or windows so team members are not silhouetted to the outside of the room (Figure 3-31). No movement should mask the fire of any of the other team members.

Figure 3-31. Points of domination and sectors of fire.
(9) On order, any member of the assault team may move deeper into the room overwatched by the other team members.
(10) Once the room is cleared, the team leader signals to the squad leader that the room has been cleared.
(11) The squad leader marks the room (IAW unit SOP). The squad leader determines whether or not his squad can continue to clear through the building.
(12) The squad reorganizes as necessary. Leaders redistribute the ammunition.
(13) The squad leader reports to the platoon leader when the room is clear.
d. Reasons for Modifying the Entry Technique. Although this technique is an effective procedure for clearing a room, leaders may be required to modify the existing action to meet their current situation. Some example reasons and methods of modifying the technique are shown in Table 3-1.
|
REASON |
METHOD |
|
Objective rooms are consistently small. |
Clear with two or three men. |
|
Shortage of personnel. |
Clear in teams of two or three. |
|
Enemy poses no immediate threat. |
One or two men search each room to ensure no enemy or noncombatants are present. |
|
No immediate threat, and speed is of the essence |
One man visually searches each room. |
Table 3-1. Reasons and methods for modifying entry techniques.
e. Three- and Two-Man Teams. When full four-man teams are not available for room clearing three- and two-man teams can be used. Figures 3-32 (below) and 3-33 show the points of domination and sectors of fire for a three-man clearing team. Figures 3-34 and 3-35 show the same thing for a two-man team. Leaders should use the entry technique blueprint when modifying their techniques.

Figure 3-35. Points of domination and sectors of fire (two-man team, corner door).
3-23. REFLEXIVE SHOOTING
Precision room clearing allows little or no margin for error. Too slow a shot at an enemy, too fast a shot at a noncombatant, or inaccurate shots can all be disastrous for the clearing team. Proper weapon ready technique, stance, aiming, shot placement, and trigger manipulations constitute reflexive shooting. Reflexive shooting techniques are used by all members of the fire team, to include M203 and M249 gunners.
a. Weapon Ready Positions. The two weapon ready positions are low ready and high ready (Figure 3-36).
(1) Low Ready Position. The butt of the weapon is placed firmly n the pocket of the shoulder with the barrel pointed down at a 45-degree angle. This position is the safest carry position. It should be used by the clearing team while inside the room, except when actually entering and clearing.
(2) High, Ready Position. The butt of the weapon is held under the armpit, with the barrel pointed slightly up, keeping the front sight assembly under the line of sight but within the gunner's peripheral vision. To engage a target, the gunner pushes the weapon out as if to bayonet the target. When the weapon leaves the armpit, he slides it up into the firing shoulder. This technique is used when moving in a single file.

Figure 3-36. Ready positions for the M16A2.
b. Stance. Feet are about shoulder-width apart. Toes are pointed to the front (direction of movement). The firing side foot is slightly staggered to the rear of the non-firing side foot. Knees are slightly bent and the upper body is leaned slightly forward. Shoulders are square and pulled back, not rolled over or slouched. The head is up and both eyes are open. When engaging targets, the gunner holds the weapon with the butt in the pocket of his shoulder.
c. Aiming with Iron Sights. The four aiming techniques all have their place during combat in urban areas, but the aimed quick-kill technique is the one most often used in precision room clearing.
(1) Slow Aimed Fire. This technique is the most accurate. It consists of taking up a steady, properly aligned sight picture and squeezing off rounds. It is normally used for engagements beyond 25 meters or when the need for accuracy overrides speed.
(2) Rapid Aimed Fire. This technique features an imperfect sight picture in which windage is critical but elevation is of lesser importance. When the front sight post is in line with the target, the gunner squeezes the trigger. This technique is used against targets out to 15 meters and is fairly accurate and very fast.
(3) Aimed Quick Kill. This technique consists of using a good spot weld and placing the front sight post flush on top of the rear peep sight. It is used for very quick shots out to 12 meters. Windage is important, but elevation is not critical with relation to the target. This technique is the fastest and most accurate. With practice, soldiers can become deadly shots at close range.
(4) Instinctive Fire. This technique is the least desirable. The gunner focuses on the target and points the weapon in the target's general direction, using muscle memory to compensate for lack of aim. This technique should be used only in emergencies.
d. M68 Close Combat Optic. The M68 close combat optic (CCO) is an excellent close combat aiming system when used properly. Remember, the M68 is not a telescope sight.
(1) Aimed Fire. This technique requires looking through the CCO with both eyes open and focusing on the target. An optical illusion places a red aiming dot in front of the firer. The dot is placed on the target then the target is engaged with fire. The aiming dot does not have to be centered in the optic. The CCO is used in the same manner at all ranges. Therefore, there is no distinction between slow aimed fire, rapid aimed fire, and aimed quick kill techniques.
(2) Instinctive Fire. This technique remains the same with the CCO.
e. Trigger Manipulation. Rapid, aimed, semiautomatic fire is the most effective method of engaging targets during precision room clearing. As each round is fired from the aimed quick-kill position, the weapon's recoil makes the front sight post move in a small natural arc. The gunner should not fight this recoil. He should let the weapon make the arc and immediately bring the front sight post back onto the target and take another shot. This two-shot combination is known as firing a controlled pair. Soldiers must practice a controlled pair until it becomes instinctive. Clearing team members continue to fire controlled pairs until the target goes down. If there are multiple targets, team members engage with a controlled pair and then return to reengage any enemy left standing or still trying to resist.
f. Shot Placement. In precision room clearing, enemy soldiers must be incapacitated immediately. Shots that wound or are mortal but do not incapacitate the target instantaneously are better than misses but may allow the enemy to return fire. While a solid head-shot is expected to instantaneously incapacitate the enemy, a target area of 5 by 8 inches may be difficult to hit when moving rapidly in a low crouch position.
(1) Members of clearing teams should concentrate on achieving solid, well-placed shots (controlled pairs) to the upper chest, then to the head (Figure 3-37). This shot placement increases the first round hit probability and allows for a second round incapacitating shot.
(2) This engagement technique is more reliable than attempting head-shots only and is easy for soldiers to learn, having been taught previously to aim at center of mass.

Figure 3-37. Lethal to incapacitating shot placement.
g. Reflexive Shooting Techniques During Limited Visibility. Reflexive shooting techniques are also used during periods of limited visibility.
(1) Visible Illumination. When using flashlights or other visible illumination, treat all engagements as day engagements and use the applicable technique as described above. Bright light shone into the enemy's eyes can limit his effectiveness; also, be aware that a flashlight marks your location as well.
(2) AN/PAQ-4 and AN/PEQ-2 Aiming Lights. When using IR aiming lights in conjunction with night vision goggles (NVGs), use the instinctive fire technique to point the weapon at the target while activating the aiming light. This technique should place the aiming dot within the field of view of the NVGs and on or near the target. Adjust placement of the aiming dot onto the target and fire. Note that target discrimination is more difficult when using NVGs. IR illumination provided by flashlights with IR filters, or the illuminator that is integral with the PEQ-2, can aid in target identification and discrimination. IR illumination is also required inside buildings when there is no ambient light.
(3) AN/PAS-13 Thermal Weapons Sight. The thermal weapons sight (TWS) offers some distinct advantages over IR viewers. It does not require any ambient light and does not bloom out when encountering a sudden light source. However, its weight and bulk are a disadvantage when performing reflexive firing techniques. With the sight in the ON position, the TWS has a power saving feature that turns off the viewer after a period of inactivity. The soldier reactivates the sight by placing his eye against the rubber eyecup. When reactivated, it takes a few seconds for the sight to cool itself down enough to regain an image. This delay is not acceptable for soldiers using TWS while conducting room and building clearing tasks. When performing precision clearing tasks, the TWS must remain in the EMERGENCY setting, which allows it to remain continuously active.
NOTE: The emergency setting on the TWS greatly reduces the battery life, which requires more frequent battery changes.
(4) When using the TWS during periods of limited visibility, it is best to use the PAQ-4 aiming light, with the AN/PVS-14 Monocular NVG for reflexive shooting engagements. Use the TWS when the slow aimed fire technique is appropriate. For daytime and high visibility periods, soldiers using the TWS should not be placed on point, or be among the numbers 1 through 3 men of a room clearing team. When employed in urban operations, soldiers must be aware that the TWS cannot detect targets through window glass. The TWS is effective in daytime for locating targets hidden in shadows.
3-24. TARGET DISCRIMINATION
Target discrimination is the act of quickly distinguishing between combatant and noncombatant personnel and engaging only the combatants. US forces engage in precision room clearing to apply discriminating combat power and limit unnecessary casualties among noncombatants. Target discrimination is vital in precision room clearing. If there are no noncombatants then there is less of a need for selective engagements. However, even if an area is known to be free of noncombatants, other soldiers moving through the area may be mistaken as enemy and engaged unless clearing team members are disciplined and well-trained in fire control and target discrimination. Even with well-trained, disciplined soldiers, precision room clearing can result in unintentional casualties among noncombatants. Commanders must recognize this and take steps to relieve the stress it causes soldiers.
3-25. MOVEMENT WITHIN A BUILDING
When operating under precision conditions, movement techniques may be modified based on the room clearing technique being used. The terrain, the enemy situation, visibility, and the likelihood of contact dictate movement techniques.
a. Individual Movement. When moving within a building, the soldier avoids silhouetting himself in doors and windows (Figure 3-38). When moving in hallways, he never moves alone—he always moves with at least one other soldier for security. The soldier should try to stay 12 to 18 inches away from walls when moving; rubbing against walls may alert an enemy on the other side, or, if engaged by an enemy, ricochet rounds tend to travel parallel to a wall.

Figure 3-38. Movement within a building.
b. Hallway Clearing Techniques. The clearing team must always be alert. Team members provide security at the breach point and to the rear. Inside buildings they provide security laterally down corridors, and upward if near stairs or landings. The two basic techniques for moving down hallways are shown in Figure 3-39. Hallway intersections are dangerous areas and should be approached cautiously (Figures 3-40 and 3-41).
(1) Serpentine. The serpentine technique is used in narrow hallways. The number 1 man provides security to the front. His sector of fire includes any enemy soldiers who appear at the far end of the hall or from any doorways near the end. The number 2 and number 3 men cover the left and right sides of the number 1 man. Their sectors of fire include any soldiers who appear suddenly from nearby doorways on either side of the hall. The number 4 man, normally carrying the M249, provides rear protection against any enemy soldiers suddenly appearing behind the clearing team.
(2) Rolling T. The rolling-T technique is used in wide hallways. The number 1 and number 2 men move abreast, covering the opposite side of the hallway from the one they are walking on. The number 3 man covers the far end of the hallway from a position behind the number 1 and number 2 men, firing between them. Once again, the number 4 man provides rear security.

Figure 3-39. Hallway clearing techniques.
(3) Clearing "T" Intersections. Figure 3-40 depicts the fire team's actions upon reaching a hallway "T" intersection when approaching from the base of the "T". The fire team is using the serpentine formation for movement.
· The team configures into a 2-by-2 formation with the numbers 1 and 2 men left, and the 3 and 4 men right. (When clearing a right-hand corner, use the left-handed firing method to minimize exposure.)
· The numbers 1 and 3 men move to the edge of the corner and assume a low crouch or kneeling position. On signal, the numbers 1 and 3 men simultaneously turn left and right, respectively.
· At the same time, the numbers 2 and 4 men step forward and turn left and right, respectively maintaining their (high) position. (Sectors of fire interlock and the low/high positions prevent soldiers from firing at another.)
· Once the left and right portions of the hallway are clear, the fire team resumes the movement formation.

Figure 3-40. T-shaped hallway intersection clearing positions.
Figure 3-41 depicts the fire team's actions upon reaching a hallway "T" intersection when approaching along the cross of the "T". The fire team is using the serpentine formation for movement.
· The team configures into a modified 2-by-2 formation with the numbers 1 and 3 men abreast and toward the right side of the hall. The number 2 man moves to the left side of the hall and orients to the front, and the number 4 man shifts to the right side (his left) and maintains rear security. (When clearing a right-hand corner, use the left-handed firing method to minimize exposure.)
· The numbers 1 and 3 men move to the edge of the corner and the number 3 man assumes a low crouch or kneeling position. On signal, the number 3 man turns right around the corner keeping low, the number 1 man steps forward while turning to the right and staying high. (Sectors of fire interlock and the low/high positions prevent soldiers from firing at one another.)
· The numbers 2 and 4 men continue to move in the direction of travel. As the number 2 man passes behind the number 1 man, the number 1 man shifts laterally to his left until he reaches the far corner.
· The numbers 2 and 4 men continue to move in the direction of travel. As the number 4 man passes behind the number 3 man, the number 3 man shifts laterally to his left until he reaches the far corner. As the number 3 man begins to shift across the hall, the number 1 man turns into the direction of travel and moves to his position in the formation.
· As the numbers 3 and 4 men reach the far side of the hallway, they too assume their original positions in the serpentine formation, and the fire team continues to move.

Figure 3-41. Hallway junction clearing.

Figure 3-41. Hallway junction clearing (continued).
c. Clearing Stairwells and Staircases. Stairwells and staircases are comparable to doorways in that they create a fatal funnel; however, the danger is intensified by the three-dimensional aspect of additional landings. The ability of the squad or team to conduct the movement depends upon which direction they are traveling and the layout of the stairs. Regardless, the clearing technique follows a basic format:
· The squad leader designates an assault element to clear the stairs.
· The squad or team maintains 360-degree, three-dimensional security in the vicinity of the stairs.
· The squad leader then directs the assault team to locate, mark, bypass and or clear any obstacles or booby traps that may be blocking access to the stairs.
· The assault element moves up (or down) the stairways by using either the two-, three-, or four-man flow technique, providing overwatch up and down the stairs while moving. The three-man variation is preferred (Figure 3-42).

Figure 3-42. Three-man flow clearing technique.
3-26. VERBAL COMMANDS AND SIGNALS
When conducting precision clearing, soldiers are very close to each other as they engage targets. The high volume of noise makes communications extremely difficult. The command and control techniques used during precision combat must consist of terms and actions that soldiers are familiar with and to which they know how to respond.
a. The use of verbal commands and signals within the assault element are extremely important. The soldier must always let others in the assault element know where he is and what he is doing.
b. As an example, terms similar to the ones listed in Table 3-2 should be a part of each soldier's vocabulary IAW unit SOP.
