FMTV: Family of Medium Tactical Vehicles

The Family of Medium Tactical Vehicles (FMTV) is a series of vehicles based on a common chassis. Trucks in the series vary by payload and mission requirements. There are two base vehicle patterns (2.5 ton and 5 ton) with multiple variants of each, including the addition of Material Handlling Equipment (MHE) to some models.

FMTV is rapidly deployable worldwide for operation on primary and secondary roads, trails, and cross-country terrain, in all climatic conditions. Commonality of parts across truck chassis variants significantly reduces the logistics burden and operating and support costs.

FMTV: Family of Medium Tactical Vehicles

The FMTV was introduced into U.S. Army service in 1996 to replace obsolete and maintenance-intensive 2.5 ton and 5 ton trucks. FMTV trucks perform local and line haul, unit mobility, unit resupply, and other missions in combat, combat support and combat service support units. The prime contractor for the FMTV series is Stewart & Stevenson Services, Inc. of Sealy, TX.
