The single mountain division formed, the 10th, was created by redesignating the 10th Light Division (Pack, Alpine). The division had been trained in fighting in snow and mountainous terrain and included many famous American skiers and mountaineers, as well as forest rangers and wildlife service men. All were volunteers and the division represented a pool of elite resources that was unique outside of the Special Service Force, Airborne forces, and the Rangers.
The 10th Mountain was organization was similar to an infantry division. However, the division had only three twelve-gun 75mm pack howitzer battalions, a special infantry antitank battalion (with eighteen 57mm guns), the infantry regiments did not have a Cannon Company, and there were only nine 37mm AT guns total in each infantry regiment. Finally, the number of motor vehicles was reduced to 421 of all types, but 5,961 horses and mules were added to provide transportation over rough terrain.
