The green beret was the official headdress of the British Commandos of World War II. It is still worn with pride by members of the Royal Marines after passing the Commando Courseand any member of the British Military who has passed the All Arms Commando Course.There are certain other military organizations which also wear the green beret because they have regimental or unit histories that have a connection with the British Commandos of World War II. These include the Australia and French and Dutch commandos and the United States Army Special Forces (Green Berets). Although it is unusual for American units to wear a distinctive headdress, it is the norm in the armed forces of the Commonwealth Nations, where most regiments wear hats or cap badges which reflect regimental battle honours and traditions.The red beret is a military beret worn by many military police, paramilitary, commando and police forces around the world. The maroon beret has become a symbol of airborne forces, though this is often known as a "red beret", particularly when referring to the British Parachute Regiment.
