2 1/2 & 5 Ton Trucks of the U.S. Military

American 2 1/2 Ton and 5 Ton cargo trucks are the backbone of Army mobility and are essential to the mission of the Marine Corps and other services as well. Since World War II, several generations of these trucks have been fielded for service in the U.S. military and continue on duty.

2 1/2 Ton and 5 Ton U.S. Military Cargo Trucks

This page shows the classification of U.S. military cargo trucks into two large families, the 2 1/2 ton ("deuce and a half") and the five ton. Within those families, each generation of truck based on one chassis design is designated as a "series" which includes many variations on the base truck for various purposes. That is, one series of chassis will be provided with specialized bodies for cargo trucks, tank trucks, vans and so forth as well as long wheel base versions and other variants.

In World War II, the 2 1/2 ton trucks were the backbone of Allied transport but by the 1970s, 5-ton trucks began to be favored over 2 1/2 ton trucks in the U.S. military. The five ton vehicles offered greater power, double the payload, and larger cargo volume than their 2 1/2 ton equivalents. While 2 1/2 ton trucks remained in large scale use, there was a shift toward their heavier 5-ton counterparts.
