Why the Marines are cannibalizing Humvees for the JLTV

The High-Mobility Multi-Purpose Wheeled Vehicle, best known as the Humvee, has been a mainstay of the United States Military for three decades, replacing the classic Jeeps. These vehicles are now giving way to the Joint Light Tactical Vehicle, or JLTV, which has some big shoes to fill.

However, the Humvee is likely going to help its successor along — by being a parts donor.


According to a release from Marine Corps Systems Command, Humvees will be capable of donating their gun turrets to JLTVs. This turret, known as the Marine Corps Transparent Armor Gun Shield, or MCTAGS, helps protect the folks manning the machine guns from enemy small-arms fire.

The MCTAGS entered service in 2005, replacing the older Gunner’s Protection Kit. One of the major advantages offered by MCTAGS is increased situational awareness for the gunners, enabling them to better see and more quickly target the enemy.

Marines recently proved that the MCTAGS can be transplanted from a Humvee to a JLTV by carrying out a proof-of-principle operation, but it’s not the only piece being donated. The Improved TOW Gunner’s Protection Kit, or IT-GPK, is also fit for transfer, alongside radios and other communications gear.

Not only will this second-hand gear enhance the survivability of the JLTV by giving gunners better situational awareness, it’ll also help the Marines save a fair chunk of change. By using existing technology, the Marines will save on development and manufacturing costs. Additionally, many who will operate the JLTV have previous experience with the Humvee’s similar configuration, meaning there’ll be no additional training — another savings.

Marines are currently carrying out the Operational Test and Evaluation process on the JLTV. The first units to get the JLTV will be the Marine Corps School of Infantry-West at Camp Pendleton, California; School of Infantry-East at Camp Lejeune, North Carolina; The Basic School at Marine Corps Base Quantico, Virginia; and Motor Transport Maintenance Instructional Company at Camp Johnson, North Carolina, which are scheduled to get the vehicles early next year.
