The utility cover was first issued in World War II, with the Herringbone Twill utility uniform issued in 1943.[5] It was based on a US Armyfield cap design[6] and a railroad engineer cap.[7] World War II Marines nicknamed it the raider cap[8] from its use by the Marine Raiders. It was made from herringbone twill until 1959, when the material changed to cottonsateen.[9][10]
