The tall fuzzy hats are known as bearskins. They are not worn by Beefeaters but are in fact part of the ceremonial uniform of the Foot Guards, who act as the personal troops of the Sovereign with the special privilege of guarding the Royal Family in both peace and war. The five regiments of Foot Guards are the Grenadier Guards, Coldstream Guards, Scots Guards, Irish Guards and Welsh Guards. Their main ceremonial duties include the Guard at Buckingham Palace, St James’s Palace, Windsor Castle and the entrance to the Tower of London. But the Foot Guards fulfill the unique dual role of being operational infantry troops as well as carrying out their ceremonial duties. They would not therefore wear the bearskin on combat duties.
