High Mobility Multipurpose Wheeled Vehicle (HMMWV)
(M998 Truck)
The High Mobility Multi-purpose Wheeled Vehicle (HMMWV) is the replacement vehicle for
the M151 series jeeps. The HMMWV's mission is to provide a light tactical vehicle for
command and control, special purpose shelter carriers, and special purpose weapons platforms
throughout all areas of the modern battlefield. It is supported using the current logistics and
maintenance structure established for Army wheeled vehicles. The HMMWV is equipped with a
high performance diesel engine, automatic transmission and four wheel drive that is air
transportable and droppable from a variety of aircraft. The HMMWV can be equipped with a
self-recovery winch capable of up to 6000 pound 1:1 ratio line pull capacity and can support
payloads from 2,500 - 4,400 pounds depending on the model. The HMMWV is produced in
several configurations to support weapons systems; command and control systems; field
ambulances; and ammunition, troop and general cargo transport.

The HMMWV is the world standard in light military trucks. It is lightweight, high performance,
four wheel drive, air transportable & droppable, land mobility system. The family includes
utility/cargo, shelter carrier, armament carrier, ambulance, TOW missile carrier and scout-
reconnaissance configuration. Payload varies by body style ranging from 1920 lbs on the 4 litter
ambulance to 5300 lbs on limited availability Expanded Capacity variant, but is generally in the
5/4T range. A basic armor package is standard on the Armament and TOW missile carrier
models. A more heavily armored, or Up-Armor HMMWV, is now being produced in limited
quantities, primarily for the Scout Platoon application. Special supplemental armor versions have
been developed for USMC requirements; unique model numbers designate these configurations.
Primary function: The HMMWV provides a variety of wheeled vehicle platforms. These are
cargo/troop carrier, armament carrier, TOW missile system carrier, shelter carrier and two
ambulance variants (2- and 4-litter). The HMMWV will also be the prime mover for the
AN/TRC-170 Radio Digital Terminal and the Pedestal Mounted Stinger System.

M1109/M1114
The M1109 and M1114 HMMWVs are an Up-Armored
Armament Carrier configuration of the HMMWV
family. The vehicles are equipped with additional armor
both on the sides and underneath to protect the crew
from small arms ammunition and mines. The weapon
mount, located on the roof of the vehicle, is adaptable to
mount either the M60, 7.62mm machine gun; M2 .50
caliber machine gun; or the MK 19 Grenade Launcher. The weapons platform can be traversed
360 degrees. This confirguration of the HMMWV is equipped with the self-recovery winch.
The Up-Armored HMMWV is designed to conduct reconnaissance and security operations as its
primary function. Up-Armored HMMWVs are organic to the scout platoons of the armored,
infantry, and mechanized infantry battalions. Up-Armored HMMWV-mounted scouts enhance
the capability of scout platoons to provide accurate and timely information about the enemy and
the area of operations.
During reconnaissance operations, the scouts provide the commander with a mobile
reconnaissance platform to perform detailed route, zone, and area reconnaissance; prevent
surprise by enemy forces; and help retain the freedom to maneuver. The speed, mobility, and
stealth of the Up-Armored HMMWV also allows the scout to extend the depth of his
reconnaissance, providing increased security and additional time and maneuver space for the
commander. Due to its small signature relative to the Cavalry Fighting Vehicle (M3), the UpArmored HMMWV provides the stealth necessary to conduct detailed reconnaissance in areas
where contact with the enemy is possible. This information is rapidly reported to higher
headquarters through secure radio means or by physical delivery (particularly during periods of
reduced electronic communications).
Security operations are also significantly enhanced by Up-Armored HMMWV-mounted scouts.
In screen missions, scouts operating independently, or in conjunction with other reconnaissance
elements, will be used to establish observation posts to the front or flank of the maneuver force,
patrol between observation posts, and cover gaps between forces. In rear areas, Up-Armored
HMMWV-mounted scouts enhance security by patrolling primary lines of communication,
providing threat early warning to rear area units, and reconnoitering potential threat landing and
drop zones.
