General Characteristics and Role
The M916 Tractor Truck is a tactical 6×6 truck tractor designed for the US Army as part of the M915 series of heavy military trucks. It is officially designated as the Light Equipment Transporter (LET). Unlike the M915 line-haul tractor, the M916 features a 6×6 (all-wheel-drive) configuration, giving it superior off-road mobility essential for transporting construction and engineering equipment in theater operations. Its primary role is to act as a prime mover for low-bed semi-trailers, such as the M172A1 (25-ton payload) and M870 (40-ton payload), transporting heavy construction loads on primary, secondary, and off-road routes. Early models were built by AM General, with later modernized versions like the M916A3 built by Freightliner.
