Under the Ordnance Department, these tractors were meant to tow artillery pieces, and were not equipped with blades like their Corps of Engineers counterparts. Later in the war, these tractors were replaced in the prime mover role by heavy trucks such as the Mack NO or purpose-built "High Speed Tractors" such as the M4, M5, or M6. Some tractors were equipped with crane attachments for ammunition and material handling.
Prior to and during the second world war the US Army called several tractors M1 Medium Tractor. Under the Ordnance Corps these "off the shelf" tractors were meant to tow artillery pieces, so were not equipped with blades like their Engineer counterparts. Eventually these were replaced by purpose built "High Speed Tractors" (HST). Some tractors were equipped with crane attachments for ammunition, and material handling.
Prior to and during World War II the United States Army called several tractors M1 Light Tractor. Under the Ordnance Corps these commercial off-the-shelf tractors were meant to tow artillery pieces so were not equipped with blades like their Engineer counterparts.

The 2+1⁄2-ton, 6×6 truck was a standard class of medium duty trucks, designed at the beginning of World War II for the US Armed Forces, in service for over half a century, from 1940 into the 1990s. Also frequently known as the deuce and a half, or just deuce, this nickname was popularized post WWII, most likely in the Vietnam war era. The basic cargo versions were designed to transport a cargo load of nominally 2+1⁄2 short tons over all terrain, in all weather. The 2+1⁄2-ton trucks were used ubiquitously in World War II, and continued to be the U.S. standard medium duty truck class after the war, including wide usage in the Korean and Vietnam Wars, as well as the first Gulf War.
