Horses in World War II were used by the belligerent nations for transportation of troops, artillery, materiel, and, to a lesser extent, in mobile cavalry troops. The role of horses for each nation depended on its military strategy and state of economy and was most pronounced in the German and Soviet Armies. Over the course of the war, both Germany (2.75 million) and the Soviet Union (3.5 million) employed more than six million horses.
