Ground Mobility Vehicle

The Ground Mobility Vehicle (GMV) is a special operations version of the Humvee used by the United States Armed Forces. Its design is mostly based on lessons learnt during Operation Desert Storm.

Design
Improvements over the Humvee include
 * Heavier suspension
 * More rugged tires
 * Improved ground clearance
 * More powerful engine
 * Open bed for improved storage and access
 * Winch for towing other vehicles (up to 4,200 pounds)
 * GPS navigation

Features
The GMV has a cruising range of 275 miles for operations behind enemy lines with only occasional resupply. GMVs feature an open rear, where an enclosed cabin would normally be. This flat bed area is used to store all the fuel, ammunition, rations and other supplies that the mission requires.

Armament

 * M2 .50 machine guns
 * M240 machine guns
 * Mk 19 or Mk 47 40mm grenade launchers
 * M249 machine guns
 * Smoke grenade launchers

Variants
Early models were based on the M1025 Humvee chassis. Later models of GMVs included versions based on the M1113 chassis. Another model based on the M1165 HMMWV can be fitted with armor kits to create an 'up-armored' GMV with additional armor plating and an optional ballistic shield around the top gunner's turret.
 * GMV-S
 * GMV-R - 75th Ranger Regiment
 * GMV-N - Navy SEALs
 * GMV-T/GMV-SD/GMV-ST - AFSOC
 * GMV-M - MARSOC

GMV 1.1
In June 2012, the United States Special Operations Command requested proposals for a GMV version 1.1. Unlike converted Humvees, the vehicle needs to be light, fast, easily transportable by air, sea, and land, with next generation communications and computing equipment. The vehicle was expected to be selected by the end of the year with production beginning in 2013. 1,300 of the new vhicles are to be in service by 2020. Vehicles entered were the Northrop Grumman Medium Assault Vehicle – Light (MAV-L), AM General's reengineered GMV design, HDT Global's Storm SRTV, the Oshkosh Special Purpose All-Terrain Vehicle (S-ATV), the Navistar Special Operations Tactical Vehicle (SOTV), and General Dynamics' Flyer. The winner was expected to be selected in May 2013. The decision for the winner was delayed until August 2013 to work through processes in dealing with vendors. The remaining contenders include the AM General upgraded GMV, the General Dynamics Flyer, and the Navistar SOTV. On 22 August 2013, General Dynamics was selected as the winner of the contract, potentially valued at $562 million. The vehicle will replace 1,092 GMVs, with funds to buy the first 101 in FY 2014 at $245,000 per vehicle. In September 2013, AM General and Navistar filed protests over the decision to award the contract to General Dynamics.
