The “Tankers,” a nickname for the Winter Combat Jacket, was developed and adopted as a winter combat uniform for tank crews. Designed for use inside the cramped tank interiors, it features a simple design with no epaulets. The standard military color “khaki” originally means yellowish-brown and derives from the Hindi word for “soil.” Before World War I, uniforms were a pale color, but the U.S. Army, participating in WWI, changed the uniform color to olive for camouflage in Europe’s vegetated battlefields; this color later became known as khaki. While tankers typically wore khaki, this is a very rare brown version that actually existed at the time. Why it was brown remains unclear, but it is still considered a “soil color.”
