Prior to and during the Second World War the US Army called several tractors M2 light tractors. 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. Eventually these were replaced by purpose built "high-speed tractors" (HST). Some tractors were equipped with crane attachments for ammunition and material handling.
