n Illumination grenades produce light at 55,000 candlepower
for about 45 seconds and are used to brighten sections of
the battlefield at night.
n Diversionary grenades produce a sound output of 183 deci-
bels and a flash of light equivalent to approximately 6. 4
million candlepower. Due to recent safety issues, this item
is under review and may be removed from the inventory.
Other similar grenades also are under review.
n Nonlethal grenades are used in military operations other
than war against noncombatants. The grenade body is a
rubber sphere that contains a fuze well liner and is filled
with a minimum of 100 rubber ball fragments. It is thrown
or launched from a cup that attaches to a shotgun.
BRIEFING: Mines may be set to detonate by control, the actions
of their victims or the passage of time. Per the Presidential
Policy of 2004, all non-self-destructing land mines were taken
out of the inventory by 2010. The M18A1 Claymore is the only
anti-personnel mine that will remain in the inventory. Efforts
to review requirements and possibly replace anti-personnel land
mines and anti-tank mines are ongoing.
Mines are considered weapons and obstacles. The typical land
mine contains a booster, body, detonator, fuse and main charge.
n The M15 anti-tank mine is used against heavy tanks and
can be fitted with a variety of fuses.
n The M16A1-series anti-personnel mine, known as the
“bouncing betty,” is a fragmentation mine that, when
activated, pops up from below the ground to a height of
about 6 feet and detonates.
n The M18A1 Claymore is a directional fragmentation mine
primarily used in protective minefields for the defense of
outposts and bivouac areas against infiltrators. Claymores
also are effective in ambush against personnel and soft-
skin vehicles. When detonated, either by electrical or
nonelectrical means, a Claymore fires a fan-shaped pattern
of steel balls in a 60-degree horizontal arc at a height of
approximately 6 feet, causing casualties within a radius of
more than 100 yards. New initiatives to replace the existing
electrical firing systems are being developed. All means of
nonelectrical initiation for the Claymore will be removed
per the Presidential Policy.
Additionally, new munitions are available for the family of
scatterable mines, which are delivered remotely by artillery.
Scatter mines have multiple fuse triggers, contain integral anti-
disturbance devices and have several different self-destruct set-
tings. They can be employed directly on top of an enemy force,
or used to protect the flanks of an attacking force.
Anti-vehicular mines use a directed-energy platter charge;
the anti-personnel mines have standing or bouncing frag-
mentation variants. These mines meet the requirements based
on the Presidential Policy of 2004.
LINEAR DEMOLITION CHARGE (LDC) FAMILY
BRIEFING: The LDC family consists of demolition systems
capable of defeating the enemy’s countermobility efforts. They
provide a clear path, up to 15 yards wide by 109 yards long, for
combat vehicles during minefield and barrier-breaching opera-
tions. They are effective against single-impulse, pressure-type,
non-blast-hardened anti-tank mines and mechanically actu-
ated anti-personnel mines. The Mk22, a 5-inch rocket motor,
is used to propel the LDCs over the minefield.
ANTI-PERSONNEL OBSTACLE-BREACHING SYSTEM (APOBS)
BRIEFING: The APOBS, a smaller version of the LDC, provides
the Marine Corps with an improved, lightweight, man-portable
capability to quickly breach anti-personnel minefields and wire
obstacles. The APOBS requires less than two minutes to set up
and deploy, and is launched from a standoff of about 35 yards
in front of the leading edge of the obstacle or minefield.
The system is designed to clear a footpath through anti-personnel minefields and wire obstacles up to 45 yards long
and 2 yards wide during combat operations. The APOBS is a
self-contained, one-shot expendable system that is transported
in two backpacks, each weighing approximately 60 pounds,
and deployed by a two-man team. APOBS uses the Mk126 Mod
1 rocket motor to propel a line charge over the obstacle, after
which the line charge will detonate following an eight-second
delay, clearing the obstacle or anti-personnel minefield.
BRIEFING: The AT4 is an expendable, shoulder-fired weapon. It
is a self-contained unit consisting of a launcher and a rocket. The
84mm system weighs nearly 15 pounds and is 40 inches long.
The projectile weighs about 4 pounds and has a muzzle velocity
of more than 300 yards per second. The warhead will penetrate
more than 40 centimeters of rolled homogenous armor.
The AT4’s maximum effective range against moving and
stationary targets is less than 300 yards. Emerging variants
have a reduced back-blast and may eventually allow firing
from confined spaces.

M72 LIGHT ANTI-ARMOR WEAPON (LAW)
BRIEFING: The M72 is a man-portable, lightweight shoulder-fired disposable rocket launcher with a disposable tube. The
M72 was superseded by the AT4, but was placed back in production in 2010 after operations in Afghanistan and Iraq
proved the value of its low cost and light weight, and because
of the lack of heavily armored targets. The current M72A7
LAW features an improved, higher-velocity rocket motor to
more accurately engage targets beyond 200 meters, an insensitive munitions warhead, and a rail to mount a laser sight or
night-vision sight. Versions under development are the M72E8
with a fire-from-enclosure (FFE) capability and the M72E10,
which also features FFE plus an anti-structure munition.
