In 1997, the U.S. Army adopted a version of the Gator known as the M-Gator. The M-Gator is now also in use with the U.S. Marine Corps. Following the upgrades of the original Gator, it is known in its current version as the M-Gator A1, and features upgrades such as rollover protection. It is the 6x4 variant, and uses the three-cylinder Yanmar diesel engine found in other Gator vehicles, and is also capable of using JP-8 fuel. The vehicle is capable of being air-dropped. The Gator has been used in Iraq and Afghanistan for supply deliveries and casualty evacuation, as it is more nimble off-road than an HMMWV. Although the M-Gator was not designed to carry equipment in the field, troops would put their gear onto the vehicles to lighten their loads when an M-Gator was available to them. M-Gators are also used by Canadian Forces in Afghanistan.
