U.S. Army basic service uniforms consisted of a winter service uniform of olive drab wool worn in temperate weather, and a summer service uniform of khaki cotton fabric worn in tropical weather. In addition to the service uniforms worn for ordinary duty and dress purposes there were a variety of fatigue and combat uniforms. Summer and winter service uniforms were worn during their respective seasons in the continental United States. During the war, the European Theater of Operations (Northwestern Europe) was considered a year-round temperate zone and the Pacific Theater of Operations a year-round tropical uniform zone. In the Mediterranean Theater of Operations, U.S. soldiers wore both seasonal uniforms.

Service stripes, or "hash marks", (awarded for every 3 years of service) were worn on the lower left sleeve. World War I Overseas Chevrons (created 1918) and/or World War II Overseas Bars, or "hershey bars" (created 1944) (awarded for each six months of service overseas) were worn on the lower left sleeve between the elbow and lower sleeve, but above the Service Stripes. The World War II Bars were worn over the World War I Chevrons. After 1953 the Service Stripes were kept on the lower left sleeve and the Overseas Service Stripes were moved to the lower right sleeve.

The Golf Jacket

The M-1943 uniform came into service in the later half of World War II. The uniform was designed as a layered system, meant to be worn over the wool shirt and trousers, and in conjunction with a wool sweater and liners in colder weather. Additionally, a fatigue-duty uniform made of 8.2-ounce heavy cotton herringbone twill (HBT) cloth was issued. The uniform consisted of a shirt, trousers, and a hat. Initially, this was a circular-brimmed "clamdigger"-style hat which was later replaced by a billed cap that was based on a design used by railroad workers. It was intended to be worn over the basic wool or cotton uniforms to provide protection during fatigue duties, but it proved to be much better material than the primary wool uniform for hot weather and so saw use as a combat uniform in nearly all of the major theaters of combat in which the US was involved.

When the coat was worn, no insignia was worn on the shirts except sew-on patches. When the shirt was worn as an outer garment, officers wore pin on insignia on the shirt. Until 1942, the officers' U.S. pin was worn on the right collar point and the officers' branch insignia was worn on the left. The officers' rank was worn on the outer ends of the shoulder loops as on the coat. After September 1942, the U.S. pin was deleted, and the rank of the wearer was displayed on the right collar point. Female members of the U.S. Army during WWII were assigned to either the Army Nurse Corps (ANC) or the Women's Auxiliary Army Corps (WAAC/WAC). The ANC preceded the WAAC/WAC so the two branches had separate uniform distinctions.a b c Kearny, Cresson H.
