Short answer
Most World War II armies wore wool or cotton uniforms in service and field versions. Field uniforms were usually in drab colors such as olive drab, khaki or field gray. Soldiers wore steel helmets and insignia showing rank and branch. The details varied by army, service and year.
Uniform categories
Three broad categories appeared in nearly every army:
- Service and dress uniforms for garrison duty, parades and formal occasions.
- Field uniforms for combat and daily duty, usually in drab colors and built to last.
- Specialist clothing for armored crews, aircrew, paratroopers, mountain troops and naval personnel.
Colors in use
The main colors were German field gray and the navy and air force shades, US olive drab, British khaki and drab, and Soviet and Japanese khaki. Colors faded and varied with dye and supply, so treat them as a rough guide rather than a fixed standard.
Examples by army
- Germany. Field gray was the army’s standard color. Field tunics came in several models, with a steel helmet and a field cap. Specialists such as Panzer crews wore black. Our WWII German uniforms and equipment guide covers these in more detail.
- United States. Olive drab wool and cotton was standard for field and service use, as covered in US WWII standard issue uniforms and equipment. The M1 steel helmet, introduced in 1941, was widely issued, and field jackets such as the M1943 were common.
- United Kingdom. British troops wore battledress, a short wool blouse and trousers introduced in the late 1930s, in khaki-drab tones. Service dress remained for formal use. See British and Canadian WWII uniforms.
- Soviet Union. Soviet soldiers wore khaki tunics and greatcoats, and the SSh-40 steel helmet was introduced in 1940. See Soviet WWII uniforms and insignia.
- Japan. Japanese forces wore khaki cotton and wool kit, with lighter clothing for Pacific theaters.

Helmets and headgear
Steel helmets were standard in most armies and differ clearly in shape and construction. The German Stahlhelm, the US M1 and the Soviet SSh-40 are the ones most often compared, as in what helmets did they wear in WWII? Field caps, peaked caps and garrison caps were worn in addition, depending on the service.
Insignia and rank
Rank and branch insignia varied by army. Shoulder marks, collar badges, sleeve stripes and branch colors were all used in different combinations. Some armies placed insignia on the chest or sleeves rather than the shoulders. Confirm insignia against a reference for the specific army and year.
What this means for collectors
- Uniforms differed within one army, so a single “typical” look is misleading.
- Dating an item often starts with its cut, color and insignia.
- Items from different countries were sometimes mixed in surplus or captured kit, so check the origin of each piece.
