APPENDIX A
Mines
A unit may use mines during security, defensive, retrograde, and offensive
operations in order to reduce the enemy's mobility. In those operations, leaders
pick the places for the mines and their men emplace them and, when required,
retrieve them (See TM 9--1345-203-12P).
The mines you will most commonly use are:
-
M14, Antipersonnel
-
M16A1, Antipersonnel
-
M18A1, Antipersonnel
-
M26, Antipersonnel
-
M15, Antitank
-
M21, Antitank
-
M24, Off-Route Antitank
ANTIPERSONNEL
M14, ANTIPERSONNEL MINE
This is a blast-type, high-explosive mine with a plastic body. A pressure of
9 to 15.8 kg (20 to 35 lb) will detonate it.
To emplace an M14 mine:
-
Remove the mine from the packing box and inspect it. If the mine is
cracked or otherwise damaged, do not use it.
-
Use the M22 wrench from the packing box to unscrew the white plastic
shipping plug from the detonator well in the bottom of the mine. Keep the
shipping plug for possible future use.
-
Inspect the firing pin's position. If it extends into the detonator well.
the mine is unsafe to use.
-
Inspect the detonator well for foreign matter. If foreign matter is
present, carefully remove it by tapping the mine against the palm of the hand.
-
Dig a hole about 10 cm (4 in) in diameter and just deep enough (about 3.8
em [1.5 in]) so that the pressure plate of the mine will extend above the
ground.
-
Make sure the ground at the bottom of the hole is solid enough to support
the mine when pressure is applied to the pressure plate. If the ground is too
soft, place a block of wood or other solid support in the bottom of the
hole.
To disarm and remove an M14 mine, reverse the steps used to arm and emplace
it.
-
Inspect the area around the mine to see if the mine has been tampered
with. If it has been, do not try to disarm it. Report the tampering to your
leader.
-
Remove the soil from the mine without putting pressure on the mine.
-
Grasp the body of the mine with one hand and insert the safety clip with
the other.
-
With the safety clip in place, turn the pressure plate so that the arrow
points to S (SAFE). That disarms the mine.
-
Remove the mine from the hole.
-
Turn the mine over and carefully remove the detonator from the detonator
well.
-
Screw the plastic shipping plug into the detonator well.
-
Clean off the mine and put it in a packing box.
M16A1, ANTIPERSONNEL MINE
This is a bounding, fragmentation mine with a metallic body. It can be set
for pressure detonation or set with a tripwire attached to a release-pin ring. A
pressure of 3.6 kg (8 lb) or more against one or more of the three prongs of the
fuze, or a pull of 1.3 kg (3 lb) or more on the tripwire, will detonate the
mine.
To emplace an M16A1 mine:
-
Remove the mine from its packing box and inspect it for damage. If the
mine is dented, cracked, or otherwise damaged, do not use it.
-
Unscrew the shipping plug from the fuze well with the closed end of the
M25 fuze wrench. Keep the shipping plug for future disarming of the mine, if
required.
-
Inspect the fuse well and flash tube of the mine for foreign matter. If
foreign matter is present, turn the mine upside down and gently tap its bottom
to dislodge the matter.
-
Set the mine down and take a fuze out of the fuze box.
-
Inspect the fuze for damage and for missing safety pins. Make sure that
the safety pins move freely in the safety-pin holes. Also make sure that the
rubber gasket is around the fuse base.
-
With the open end of the wrench, make sure that the bushing adapter on the
fuze well is tight.
-
Screw the fuze assembly into the fuze well with the fuze wrench.
-
Dig a hold about 15 cm (6 in) deep and 13 cm (5 in) in diameter.
-
Put the mine in the hole.
To disarm and remove an M16A1 mine, reverse the steps used to arm and emplace
it.
-
Check the mine and the area around it to see if the mine has been tampered
with.
-
If it has been, do not try to disarm it.
-
Report the tampering to your leader.
-
Uncover the top of the mine.
-
Insert the positive safety pin through the positive safety pin hole.
-
Insert the locking safety pin through the locking safety pin hole opposite
the release-pin ring.
-
Insert the interlocking safety pin between the positive safety pin and
locking safety pin.
-
If tripwires are attached to the release-pin ring, cut all of them after
the safety pins have been inserted.
-
Remove the dirt from around the mine and then lift the mine out of the
hole.
-
Unscrew and remove the fuze assembly.
-
Replace the plastic shipping plug in the fuze well.
-
Replace the mine and fuze in the packing box.
M18A1, ANTIPERSONNEL MINE (CLAYMORE)
This is a curved, rectangular mine containing C4 explosive and 700 steel
balls. It can be fired electrically or nonelectrically.
The Claymore projects 700 steel balls in a fan-shaped pattern about 2 meters
(6.6 ft) high and 60 degrees wide to a range of 50 meters (165 ft). These balls
are effective as far as 100 meters (328 ft) and are dangerous up to 250 meters
(825 ft) forward of the mine.
To emplace a Claymore for command detonation:
-
Remove the electrical firing wire, the firing device, and test set from
the bandoleer. Do not take the mine out of the bandoleer.

wire from the stake, and reroll the firing wire.
-
Pick up the mine and put it in the bandoleer.
-
Remove the firing wire from the stake at the firing position and put it in
the bandoleer.
To emplace a Claymore with a tripwire:
-
Emplace and aim the mine to cover the desired kill zone.
-
Put an anchor stake (1) about 1 meter (3.3 ft) to the rear of the mine and
attach the firing wire to it, leaving about 1.5 meters (5 ft) of slack. Do not
insert the blasting cap into the mine at this time.
-
Unroll the firing wire to a point about 20 meters (66 ft) to either the
left or right front of the mine. Put an anchor stake (2) at that point.
-
Attach a clothespin (or other improvised device) to stake (2) with its
closed end pointing toward the kill zone. The clothespin can be tied or nailed
to the stake.
-
Move across the kill zone and put in another stake (3).
-
Attach the trip wire to stake (3) and unroll the tripwire to stake (2).
-
Attach the end of the tripwire to a C-ration plastic spoon or some other
nonconductor of electricity. Connect the tripwire and spoon before setting up
the mine.
-
Prepare the firing wire at stake (2) for connection to the clothespin by
cut- ting one strand of the firing wire and forming two bare wire loops that
can fit over the ends of the clothespin. (Do that before setting up the mine.)
-
Slide the loops over the ends of the clothespin and tighten them to fit in
the grooves of the clothespin.
-
Insert the tripwire spoon into the jaws of the clothespin. The tripwire
should be about ankle-high and not too tight.
