Prior to the outbreak of World War I full dress uniforms were universal issue for all regiments of the British Army when on "home service" in Britain itself. Line infantry and Foot Guards, dragoons, Life Guards and Royal Engineers all wore scarlet tunics. The Royal Regiment of Artillery, hussars, all but one lancer regiment, and all support corps wore dark blue uniforms. Only Rifle regiments wore green. Full dress varied greatly in detail, according to the arm of service or in many cases the individual regiment.
