MARINE CORPS WEAPONS & VEHICLES
AMPHIBIOUS COMBAT VEHICLE (ACV)
BRIEFING: The ACV program is designed to provide an
advanced-generation, armored amphibious combat vehicle
to replace the AAV7. The ACV will be the primary means of
tactical mobility for the Marine rifle squad at sea and ashore.
The ACV will possess ground mobility and speed similar to the
M1A1 tank during sustained operations ashore and have the
capability to provide organic, direct fire support to dismounted
infantry in the attack. The plan to develop the ACV is divided
into three phases: ACV 1. 1, ACV 1. 2 and ACV 2.0.
ACV 1. 1 will support expeditionary mobility capability and
capacity with balanced levels of performance, protection and
payload. It will be capable of utilizing water obstacles, including the sea within the littoral operating area, as maneuver
space. This tactical level of water mobility will enable shore-to-shore maneuver and complement the operational capability
of the AAV. The ACV 1. 1 will provide two infantry battalions of
expeditionary protected mobility capacity.
ACV 1. 2 is expected to bring improved capability and capacity to the ACV. The degree of improvements will be driven by
lessons learned from ACV 1. 1; however, one capability that will
be sought is the ability to self-deploy and recover from naval
amphibious shipping. Additionally, ACV 1. 2 will bring new variants for recovery and command-and-control functions. Current
plans indicate an intention to procure 490 ACVs in phase 1. 2.
ACV 2.0 is a planning construct that details a desired
capability, not a specific, singular vehicle type or craft. The
capability sought by the Marine Corps for ACV 2.0 is the ability
to achieve high water speed in ship-to-shore operations. This
currently is a science and technology effort led by the Marine
Corps Warfighting Lab as well as the Office of Naval Research.

LIGHT ARMORED VEHICLE (LAV)
BRIEFING: The Marine Corps has more than 900 LAV-A2s.
Seven configurations of the Family of LAV (FOLAV) are in
service, including the LAV- 25, armed with a M242 25mm
chain gun; LAV-Anti-Tank, armed with the TOW missile
system; LAV-Command-and-Control variant, equipped with
a communications suite; LAV-Logistics variant; LAV-Mortar
variant; the LAV-Recovery variant; and LAV-Mobile Electronic
The LAV mission profile centers on conducting reconnaissance, security and economy-of-force operations, and, within
its capabilities, limited offensive or defensive operations that
exploit the unit’s mobility and firepower. LAVs can cross rivers and streams and traverse rough terrain at relatively high
speed. During Operation Iraqi Freedom, the Corps mobilized
most of its LAV inventory to drive more than 600 miles inland
from Kuwait to Tikrit, north of Baghdad, demonstrating the
mobility requirement of the modern MAGTF. LAVs continued
to provide critical mission capabilities to Marine Corps.
A service life extension program (SLEP) was initiated in
2005 primarily to address obsolescence issues. In addition,
this upgrade replaced the LAV- 25’s Generation I thermal sight
with a Generation II system, with greater ranges for target
detection, recognition and identification. The new sight incor-
porates an integrated laser rangefinder, fire-control computer,
target motion indicator and target coordinate computation.
The SLEP efforts enhanced the survivability and lethality of
the LAV- 25 platform, extended the LAV’s service life and
redesignated the LAV configurations as LAV-A1.
The second upgrade to the FOLAV became the LAV-A2
configuration standard. The LAV-A2 project involved developing and installing an internal and external ballistic protection
upgrade package, an automatic fire-suppression system for the
interior of the vehicle, engine and cooling system upgrades, a
280-amp alternator upgrade and a Generation II suspension
upgrade to support the added weight of the new armor. The
suspension upgrade includes new struts/steering knuckles,
torsion bars, shocks and mounts, and drive shaft. The A2
upgrade also included a power pack enhancement package that
improves systems cooling, increases engine horsepower and
eases maintainability. A new high-performance muffler and
thermal shroud were added that reduced emissions, vehicle
weight and thermal signature.
The Anti-Tank Modernization (ATM) program, currently in
the Production Phase, will restore the supportability and mission effectiveness of the LAV-ATA2s by providing improved
reliability, availability and maintainability of the turret system. This will be achieved through the following mission suite
upgrades: multishot capability, the ability to acquire targets
while on the move with an improved thermal sight, and an
advanced fire-control system capable of firing the current and
next-generation heavy anti-armor missiles.
The Obsolescence (OB) program, currently in the
Engineering Manufacturing and Development Phase, is
addressing obsolescence issues. OB will integrate a new engine
and transmission. Additionally, OB will upgrade the driver’s
instrument panel and slip ring on the LAV- 25.

M1A1 ABRAMS MAIN BATTLE TANK (MBT)
BRIEFING: The M1A1 MBT continues to be an integral part of
the combined arms team of the MAGTF by providing a capability for armored maneuver and lethal and survivable close tank
support to infantry. The Marine Corps M1A1 has been providing this service since 1989 and is planned to continue through
