The King's Guard at Wellington Barracks in London 🇬🇧

Under Winter Order, soldiers wear single-breasted greatcoats, while officers and warrant officers don a double-breasted version. The greatcoat has a long military history, first adopted during the Napoleonic era to withstand harsh winter weather. While the military greatcoat was standard issue for frontline British soldiers until the 1950s, it is now reserved solely for ceremonial duties 🇬🇧
