The JLTV is jam-packed with features, options and settings, so service members shouldn’t expect to hop in and run it without a learning curve (right or wrong, that’s the reality).

According to Marine Corps math, Barbieri’s diligence will save the Marine Corps more than 900,000 man-hours of maintenance and more than $140 million over the lifespan of the JLTV platform.

So far, the service has acquired 20,000 vehicles. The Army began fielding the JLTV in 2019, the same year the Marine Corps began receiving its first vehicles.

As a “joint” vehicle, the JLTV is used primarily by the Army, but also in great numbers by the Marine Corps, and smaller numbers by the Air Force and Navy.
