The Service Dress of the King Edward’s Horse remained unchanged from 1910 through to the disbandment of the Regiment in 1924. This uniform for both Officers and Other Ranks was of standard cavalry pattern of khaki forage cap, tunic and overalls. Shoulder chains were dispensed with for Service Dress.
Officers carried the 1908 pattern cavalry Mark 1 sword and Other Ranks were equipped with .303 SMLE Mark 1 rifles and 1903 pattern, Mounted Infantry leather 50 round bandoliers. The leather bandolier was 50 inches long and 3.25 inches wide and held 50 .303 cartridges. It was made up of four sections each x 10 cartridges, plus one section x 6 cartridges and one section x four cartridges. Towards mobilisation for war in 1914 all ranks were equipped with swords.Figure 99: A Trooper of King Edward’s Horse in Service Dress uniform with his partner circa 1914 with 1903-pattern, Mounted Infantry leather 50 round .303 bandolier and King Edward’s Horse Regimental headdress badge.
