The M1114 is a High Mobility Multipurpose Wheeled Vehicle (HMMWV) that is used by the United States Army and Marines. Its primary purpose is reconnaissance and patrol missions but it has also been used in peacekeeping missions and activities in a number of countries (Afghanistan, Iraq, Somalia and Haiti). The M1114 provides perimeter ballistic protection, protection from improvised explosive devices (IEDs), mine and overhead blast protection as well as offering gunner shield and gunner protection kits.

M114 Description

The M1114 is a 1.25 ton capacity HMMWV. It is diesel powered, has 4 doors and can operate on either 2 wheel or 4 wheel drive depending on the terrain. It is 16.2 feet long, 7.5 feet wide and approximately 6 feet tall. It has an automatic transmission and can usually carry four passengers in addition to one gunner.


Very similar in appearance to the M1025, the M1114 has the same rear hatch that gives them the “turtle-like” look. Major design changes in the M1114 include a built in air conditioning unit placed over the back left wheel as well as an upgrade to the design of the bulletproof windows which makes them more streamlined.

Like all HMMWVs, the M114 has the capability for on and off road travel. One drawback in the design is that it is not capable of functioning in water. It can however, be modified by the addition of an air intake and exhaust that will allow it to cross water that is up to 5 feet deep. It also has run-flat wheel inserts that allow it to continue moving after losing compression in a tire.


The M1114 gives protection from 7.62mm Armor-piercing ammunition, as well as offers blast protection above and below it from 155mm artillery. It has also been designed so that the front of the vehicle can survive a 12 pound TNT charge detonation, while the rear can survive the detonation of a 4 pound charge. A smoke grenade launcher can be mounted to the roof of the M1114 (one at each corner). These can be fired safely by a passenger inside the vehicle.

The vehicle has a single weapons station mounted on the roof that is designed to accommodate a single machine gun. The most commonly used guns at this station are the M2 .50 caliber, M249 5.56mm, or M240 series. Less commonly used are the M134 7.62mm 6-barreled minigun, and the GAU-19/A 3-barreled .50 caliber.
