EMPLOY AN M18A1 CLAYMORE MINE TASK: Employ the M18A1 Claymore Mine CONDITIONS: Given an M18A1 Claymore mine, an M57 firing device, an M40 test set, and a firing wire with blasting cap, packed in an M57 bandoleer; a designated installation site; a firing position at least 16 meters from the installation site; a sandbag; and two wooden stakes. STANDARDS: Install the Claymore facing the center mass of a kill zone. Perform a circuit test and installation of wire and blasting cap.

EMPLOY AN M18A1 CLAYMORE MINE The M18 Claymore, a directional fragmentation mine, is 8- 1/2 inches long, 1-3/8 inches wide, 3-1/4 inches high, and weighs 3-1/2 pounds. The mine contains 700 steel spheres (10.5 grains) and 1-1/2 pound layer of composition C-4 explosive and is initiated by a No. 2 electric blasting cap. The M18 command-detonated mine may be employed with obstacles or on the approaches, forward edges, flanks and rear edges of protective minefields as close-in protection against a dismounted Infantry attack.

EMPLOY AN M18A1 CLAYMORE MINE The M18A1 mine is primarily a defensive weapon. It may be employed to a limited extent in certain phases of offensive operations. The M18A1 has the same basic capabilities as antipersonnel mines and can be used in most situations where other types of antipersonnel mines are employed. In addition, the M18A1 has the capability of being sighted directionally to provide fragmentation over a specific area and does not necessarily rely upon chance detonation by the enemy. The M18A1 is adaptable for covering the ranges between maximum hand grenade throwing distance and the minimum safe distance of mortar and artillery supporting fires

EMPLOY AN M18A1 CLAYMORE MINE Inventory: Inventory the M18A1 Claymore mine. Account for all accessories in the bandoleer. Items are as follows: M7 Bandoleer Firing Wire w/M4 Blasting Cap M40 Test Set M57 Firing Device M18A1 Claymore mine

EMPLOY AN M18A1 CLAYMORE MINE CONDUCT A CIRCUIT TEST Remove the electrical wire and accessories while leaving the mine in the bandoleer Remove the dust cover from the connector of the M57 firing device and from the female connector of the M40 test set Plug the test set into the firing device Position the firing device bail to the FIRE position

EMPLOY AN M18A1 CLAYMORE MINE NOTE: The safety bail on the M57 electrical firing device has two positions. In the upper SAFE position, it acts as a block between the firing handle and the pulse generator. In the lower FIRE position, it is clear of the firing handle and allows the pulse generator to be activated.

EMPLOY AN M18A1 CLAYMORE MINE CONDUCT A CIRCUIT TEST cont: Actuate the handle of the firing device with a firm, quick squeeze, observing the flash of light through the window of the test set NOTE: The flashing light indicates that the M57 firing device and the M40 test set are functioning properly Remove the shorting plug cover from the connector of the firing wire and from the end of the test set

EMPLOY AN M18A1 CLAYMORE MINE Conduct a Circuit Test cont: Plug the connector of the firing wire into the test set WARNING: The blasting cap must be placed under a sandbag, behind a tree or in a hole in the ground to protect the person performing the circuit check in case the blasting cap detonates.

EMPLOY AN M18A1 CLAYMORE MINE Conduct a Circuit Check cont; Place the M57 firing device bail in the fire position and actuate the firing handle NOTE: The lamp in the window of the M40 test set should flash Place the firing device on SAFE, remove the M57 firing device and M40 test set Place the shorting plug cover on the firing wire

EMPLOY AN M18A1 CLAYMORE MINE Install the M18A1 Claymore mine Tie the shorting plug end of the firing wire to a fixed object, such as a stake or tree at the “firing position” Place the bandoleer on your shoulder Unroll the firing wire to the selected installation position

EMPLOY AN M18A1 CLAYMORE MINE NOTE: The firing wire is laid from the firing position to the mine installation site because the blasting cap end is on the inside of the firing wire spool. Aim the mine Remove the mine from the bandoleer Open both pair of legs to a 45% angle with two legs facing to the front and two legs facing to the rear of the mine

EMPLOY AN M18A1 CLAYMORE MINE

EMPLOY AN M18A1 CLAYMORE MINE Push the legs 1/3rd of the way into the ground with the mine facing in the desired direction of fire. In windy areas or when the legs cannot be pressed into the ground spread the legs as far as they will go so that the legs are to the front and rear of the mine and the mine will not tip over select an aiming point at ground level about 50 meters (150 feet) in front of the mine Position one eye about 6 inches to the rear of the sight

EMPLOY AN M18A1 CLAYMORE MINE On a Knife-edge sight, align the two edges of the sight with the aiming point

EMPLOY AN M18A1 CLAYMORE MINE

EMPLOY AN M18A1 CLAYMORE MINE Arm the Mine Secure the firing wire about 1 meter to the rear of the mine so the mine will not become misaligned if the firing wire is disturbed Unscrew one of the shipping plug priming adapters from the mine Slide the slotted end of the shipping plug priming adapter onto the firing wire of the blasting cap between the crimped connections and the blasting cap

EMPLOY AN M18A1 CLAYMORE MINE Pull the excess wire through the slotted end of the adapter until the top of the blasting cap is firmly seated in the bottom portion of the shipping plug priming adapter Screw the adapter, with the blasting cap, into the detonator well WARNING: Ensure that the face of the mine marked “Front Toward Enemy” and the arrows on the mine point in the direction of the enemy

EMPLOY AN M18A1 CLAYMORE MINE Recheck the mine Camouflage the mine Bury the firing wire (if possible) from the mine back to the firing position

EMPLOY AN M18A1 CLAYMORE MINE

EMPLOY AN M18A1 CLAYMORE MINE NOTE: To ensure that the mine will function properly after installation, retesting the firing circuit will check for any break in the wire may have occurred during installation NOTE: Friendly troops within 250 meters to the front and sides and 100 meters to the rear of the mine must be under cover WARNING: You must be behind cover or in a fighting position when retesting the circuit on a claymore mine with the blasting cap inserted in the detonation well

EMPLOY AN M18A1 CLAYMORE MINE Fire the Mine Remove the dust cover from the firing device and firing wire Connect the firing wire to the firing device Position the firing device safety bail in the fire position Actuate the firing device handle with a firm, quick squeeze Assume a prone position behind cover
