Performance Steps

1.  
Inventory the M18A1
Claymore mine bandoleer, accounting
for all accessories. (figure 071-325-4425-1).






Figure 071-325-4425-1.
Components of the M18A1 Claymore mine

 

WARNING:
During
testing and installation, keep the
M57 firing device in your possession
to prevent accidental firing by
someone else.

2.  
Conduct a circuit test at
the firing point (figure 071-325-4425-2).






Figure 071-325-4425-2.
Circuit test of the M57 firing device
and M40 test set

 

a.
Remove the electrical wire
and accessories while leaving the mine
in the bandoleer.

b.
Remove the dust cover from
the connector of the M57 firing device
and from the female connector of the
M40 test set.

c.
Plug the test set into the
firing device.

d.
Position the firing device
bail to the FIRE position.

e.
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 M40 test set are functioning
correctly.

f. 
Remove the shorting plug
cover from the connector of the firing
wire and from the end of the test set.

g. Plug the connector of the
firing wire into the test set (figure 071-325-4425-3).







Figure 071-325-4425-3.
Circuit test of the M18A1 Claymore
mine firing system

 

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.

h.
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.

i.  
Place the firing device on
SAFE, remove the M57 firing device and
M40 test set.

j.  
Place the shorting plug
cover on the firing wire.

3.   Install the M18A1 Claymore mine.

a. Tie the shorting plug end
of the firing wire to a fixed object,
such as a stake or tree at the firing
position (figure 071-325-4425-4).



Figure 071-325-4425-4.
Firing wire secured

 

b.
Place the bandoleer on your
shoulder.

c.
Unroll the firing wire to
the selected installation position.

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.

4.   Aim the mine.

a.
Remove the mine from the
bandoleer.

b. Open both pairs of legs to
a 45-degree angle with two legs facing
to the front and two legs facing to
the rear of the mine (figure 071-325-4425-5).






Figure 071-325-4425-5.
Placing and aiming the mine

 

c.
Push the legs about
one-third 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 (about 180 degrees) so
the legs are to the front and rear of
the mine and the mine will not tip
over.



Figure 071-325-4425-6.
Aiming knife-edge sight

 

d.
Select an aiming point at ground level
about 50 meters (150 feet) in front of
the mine (figure 071-325-4425-6).

e.
Position one eye about 6
inches to the rear of the sight.

(1)  On a knife-edge
sight, align the two edges of the
sight with the aiming point (figure 071-325-4425-7
and figure 071-325-4425-8).

Aiming knife-edge sight (continued)

 





Figure 071-325-4425-8.
Aiming knife-edge sight (continued)

 

(2) 
On a slit-type peep sight,
align the groove of the sight with the
aiming point that is 2.5 meters (8
feet) off the ground (figure 071-325-4425-9
and figure 071-325-4425-10).





Figure 071-325-4425-9.
Aiming slit-type peep sight

 





Figure 071-325-4425-10.
Aiming slit-type peep sight
(continued)

 

Note. The aiming point should be in the center of the desired
area of coverage with the bottom edge
of the peep sight parallel to the
ground that is to be covered with the
fragment spray.

5.   Arm the mine.

a.
Secure the firing wire
about one meter to the rear of the
mine so the mine will not become
misaligned if the firing wire is
disturbed.

b.
Unscrew one of the shipping
plug priming adapters from the mine.

c.
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.

d.
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
(figure 071-325-4425-11).







Figure 071-325-4425-11.
Arming the mine

 

e.
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.

f. 
Recheck the aim of the
mine.

6.   Camouflage the mine.

7.   Bury the firing wire (if possible) from the mine
back to the firing position.

Note. The firing position should be in a hole or covered
position at least 16 meters to the
rear or the side of the emplaced mine.

WARNING:
The M40 test
set must be used during retest of
the circuit.

8.  
Repeat step 2 to test the
circuit after the firing wire is laid
out and the cap is placed inside the
mine to see if there are any breaks in
the wire (figure 071-325-4425-12).







Figure 071-325-4425-12.
Retesting the circuit

 

Note. To ensure that the mine will function properly after
installation, retest the firing
circuit to check for any break in the
wire that 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.

9.   Fire the mine.

a.
Remove the dust cover from
the firing device and firing wire.

b.
Connect the firing wire to
the firing device.

c. Position the firing device
safety bail in the FIRE position
(figure 071-325-4425‑13).





Figure 071-325-4425-13.
Firing device in the SAFE position

 

d.
Actuate the firing device
handle with a firm, quick squeeze.

e.
Assume a prone position
behind cover.

Note. The mine is most effective when employed against targets
20 to 30 meters in front of it.

Evaluation Preparation: 

Setup: During training, use only inert blasting caps and mines. At
the test site, place one M7 bandoleer
containing an inert M18A1 Claymore mine, an
M57 firing device, and an M40 test set.
Check to make sure each mine is complete and
serviceable. Place one wooden stake in the
ground at the test position and another at
the mine emplacement point. The distance
between the emplacement point and firing
point must be no less than 16 meters. The
stake at the aiming point should be painted
red or some other distinguishable color.
Once the soldier has emplaced the mine and
completed the circuit test, assume a prone
position and visually confirm that the mine
is correctly aimed. To assist you, place
stakes one meter on each side of the aiming
point stake. The height of the stakes should
not exceed one foot above the ground. During
the circuit test, do not attempt to observe
the flash on the M40 test set because it may
interfere with the soldier’s performance.
Throughout the evaluation, if the soldier
states that he cannot see the flashing
light, tell him "CONTINUE WITH THE
TEST."

Brief
Soldier: Tell the soldier to perform a
circuit check on the firing wire and then
install the mine. Camouflaging and burying
the wire are not covered during the
evaluation.
