MARINE CORPS WEAPONS & VEHICLES
SMALL ARMS AND MACHINE GUNS
BRIEFING: Marines have available for combat use a wide range
of grenades for assault and other missions:
■ The M67 fragmentation grenade has an effective range of
approximately 50 feet.
■ Riot-control grenades produce a thick cloud of irritant
vapor/smoke that causes eye, throat and lung irritation.
■ Signaling grenades, such as the M18 colored-smoke grenade,
produce clouds of green, yellow, red and violet smoke. Also useful for screening is the AN-M8 HC grenade, which produces a
thick cloud of white smoke.
■ The incendiary grenade, M14/thermite, is used to melt large
battlefield items, rendering them useless. This grenade contains
a filler of aluminum and iron oxide that burns for approximately
40 seconds at close to 4,000 degrees Fahrenheit.
■ Illumination grenades produce light at 55,000 candlepower
for about 45 seconds and are used to brighten sections of the battlefield at night.
■ Diversionary grenades produce a sound output of 183 decibels 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.
■ 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.
■ The M15 anti-tank mine is used against heavy tanks and can
be fitted with a variety of fuses.
■ 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.
■ 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 settings. 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 fragmentation variants. These mines meet the requirements based on the
Presidential Policy of 2004.
LINEAR DEMOLITION CHARGE (LDC)
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 operations. They are effective against single-impulse, pressure-type,
non-blast-hardened anti-tank mines and mechanically actuated
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.
A T 4
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.
CON TRACTOR: ...........SAAB Bofors
FGM- 148 JAVELIN MEDIUM
ANTI-ARMOR SYSTEM (M98A2)
BRIEFING: The Javelin missile is a highly maneuverable, fire-and-forget weapon featuring an advanced tandem warhead
