Within the U.S military, jeeps were used by every branch. In the U.S. Army, an average of 145 units were assigned to each infantry regiment. Around the world, jeeps took part in every theater of war overseas — in Africa and the Pacific Theater, the Western Allied invasion of Europe in 1944, as well as the Eastern Front. Jeeps became so ubiquitous in the European battle theater that some German troops believed that each American soldier was issued their own jeep.
