The vehicles were first used in combat in Italy by the British Eighth Army. Later, Sextons took part in the invasion of France and subsequent Battle of Normandy and the campaign in north-western Europe. During the D-day landings, a number of Sextons were ordered to fire from their landing craft as they approached the beaches although the fire did not prove to be very accurate. After the war a number of units were equipped with the Sexton as part of the British Army of the Rhine (BAOR).
