British Army uniform and equipment in World War I

The British Army used a variety of standardized battle uniforms and weapons during World War I. According to the British official historian Brigadier James E. Edmonds writing in 1925, "The British Army of 1914 was the best trained best equipped and best organized British Army ever sent to war". The value of drab clothing was quickly recognised by the British Army, who introduced Khaki drill for Indian and colonial warfare from the mid-19th century on.
