    Breaching

    A part of room clearing is the ability to gain access quickly to

    the rooms to be cleared. Breaching techniques vary based onthe type of construction encountered and the types ofmunitions available to the breaching element. Techniques rangefrom simple mechanical breaching to complex, specializeddemolitions. If possible, conduct the breach to allo the teamto continue movement ithout aiting at the breach !entry"point. #eception should be used to confuse the enemy as to thelocation of the primary entry point. This can be achieved byusing stun grenades in an area other than the actualbreach$entry point.

    Opening of Doors if not Locked

    If the team knos that the door isn%t locked. &ne of to simpleorders are used "pull and go" or "Push and go".A closed door is considered locked in all cases hen a breacheris present, assuming the breacher has the means available todefeat the door.

    'ull and go.(hen the team reaches a door &perator ) gives the order "pulland go". &n this one operator steps out of the stack, moves tothe the door, and pulls it open hen operator ) signals "GO",by nodding his head three times. This could also be done by

    'ush and go. This is done the same ay as +pull and go+ except that the dooropens inards. In most cases operator ) opens the doorhimself.

    xperienced teams do this automatically ithout anycommands.

    Mechanical Breaching The mechanical breach requires increased physical exertion byone or more soldiers using hand tools such as axes, sas,crobars, hooligan tools, or sledgehammers. The mechanicalbreach is not a preferred primary breaching method because itcan be time-consuming and defeat the element of surprise. semechanical breaching as a backup to a ballistic or explosivebreach.

    Ballistic breachA useful method of breaching is the shotgun ballistic breach forforced entry of standard doors. se a *3-gauge shotgun loadedith buckshot or slugs to breach most standard doors quickly.

    (hen done properly the shotgun breach requires only a feseconds. The to standard techniques of shotgun breaching arethe doorknob breach and the hinge breach. (hen attemptingeither technique, the gunner is announcing his presence byusing the shotgun and is completely exposed to 4re through thedoor. Therefore, exposure time must be minimized and theoperator ) must be ready to gain entry and return 4re as soonas possible. (hile holding the stock of the shotgun in thepocket of his shoulder, the gunner places the muzzle tightly

    against the door, and aims don at a 56-degree angle. If theshotgun muzzle is not held tightly against the door, splattermay occur that could a7ect friendly troops. Also, buckshot andri8ed slugs can over penetrate doors and may kill or oundoccupants in the room

    #oorknob Breach9or the doorknob breach, the aim point is a spot halfaybeteen the doorknob and the frame, not at the doorknobitself. The gunner 4res to quick shots in the same location,ensuring that the second shot is aimed as carefully as the 4rst.(eak locks may 8y apart ith the 4rst shot, but the gunnershould alays 4re tice. /ome locks that appear to be blonapart have parts still connected that ill delay entry. If the lockis not defeated by the second shot, the gunner repeats theprocedure.

    :inge Breach The hinge breach technique is performed much the same as thedoorknob breach, except the gunner aims at the hinges. :e4res three shots per hinge. The 4rst at the middle, then at thetop and bottom :e 4res all shots from less than an inch aayfrom the hinge. Because the hinges are often hidden from vie,the hinge breach is more di;cult.

    &nly use small arms !6.6>" as a ballistic breach on doorknobs

    and hinges as a last resort.

     

    Do not attempt to open the door by hand. If the door islocked, this action will alert any combatants inside ofthe room of your intentions and possibly expose thebreacher to re through the doorway.

    !xplosi"e entry The use of explosive charges to breach doors or alls onbuildings and aircraft is an excellent /&'. Althoughunfortunately, because of a lack of training, understanding,expertise, and the cost involved, explosive entry is not acommon standard for entry teams. The to prime advantagesof explosive method of entry ?& are the almost guaranteed

    entry and the stun e7ect on the occupants in the room.veryone should be stunned to a certain degree, making iteasier to dominate and control the room. :oever, it is notrecommended that the breaching charge be placed on doors oralls leading into the actual room here the hostages arebeing held.xplosive ?& has been perfected to such a degree that thesecondary fragmentation from the door and the risk of over-pressure in@uries to the hostages have been all but eliminated.

    xplosives should only be handled by experienced bombtechnician, personnel, or specially trained operators.

If the door must be breached by more conventionalnon-explosive methods, e.g. battering ram, boot or cro bar,then stun grenades should be dropped through broken indosto temporarily disorient the occupants.

    Interior alls generally require much less explosive to create asatisfactory breach than do exterior, load-bearing alls. Aneasily fabricated silhouette charge can further reduce theamount of explosive needed to breach plyood, /heetrock, orlight plaster alls. It can also be used to breach ooden ormetal doors. This charge can be emplaced quickly and createsa hole large enough for a man to move through.

    #ubber Band %harge The rubber band charge is another easily fabricated lighteightdevice that can be used to remove the locking mechanism ordoorknob from ooden or light metal doors, or to break a

    standard-size padlock at the shackle.

    pigtail for priming the charge.

    !3" Attach the charge to the doorknob !or locking mechanism"by putting the loose end of the rubber band around the knob.

     The charge should be placed beteen the knob and thedoorframe. This places the explosive over the bolt that securesthe door to the frame.

    lexible Linear %harge

    &ne of the simplest 4eld-expedient charges for breachingooden doors is the 8exible linear charge. It can be made inalmost any length, and it can be rolled up and carried untilneeded. It is e7ective against hollo-core, particle-4lled, andsolid ood doors. (hen detonated, the 8exible linear chargecuts through the door near the hinges.
