Green beret
The 10th Special Forces Group (Airborne) had many OSS World War II veterans in their ranks when it was formed in 1952. They began to unofficially wear a berets of varying colour while training. The color green became favored because it was reminiscent of the World War II British Commando-type beret. The 10th Special Forces Group (Airborne) deployed to Bad Tolz, Germany in September 1953. The remaining cadre at Fort Bragg formed the 77th Special Forces Group. Members of the 77th SFG began searching through their collections of berets and settled on the Rifle Green colour of the British Rifle Regiments (as opposed to the Lovat Green of the Commandos) from Captain Mike de la Pena's collection. Captain Frank Dallas had the new beret designed and produced in small numbers for the members of the Special Forces.
Shades of green
Rifle green was originally adopted by rifle regiments in the 18th century, including the famous 95th Rifles of the Napoleonic Wars. As the traditional role of riflemen was that of marksmen and skirmishers who attacked behind the cover of trees, a dark green uniform was adopted as an early form of camouflage, as opposed to the colorful uniforms worn by other soldiers of the period. The vegetable based dyes used during the 18th and early 19th centuries were not fast, frequently fading after exposure to the elements to lighter shades of green or even brown. While this had advantages in terms of reduced visibility on active service, it did not make for a smart appearance on the peace-time parade ground. Accordingly, the color of the rifleman's uniform was progressively darkened until it approached black. After 1890 the development of chemical dyes permitted the adoption of the stable shade of rifle green now worn. In the U.S. armed forces, the green beret may be worn only by soldiers awarded the Special Forces Tab, signifying they have been qualified as special forces soldiers. The special forces beret is officially designated "beret, man's, wool, rifle green, army shade 297". Previously, rifle green uniforms had been issued to Hiram Berdan's elite 1st and 2nd United States Sharpshooters during the American Civil War.
