Desert Combat – worn by dismounted troops conducting medium to high levels of activity in desert type environments with temperatures exceeding 40 degrees Celsius. Desert Patrol – worn by drivers/armoured troops conducting lower levels of activity in desert type environments exceeding 40 degrees Celsius. Temperate Combat – worn by dismounted troops for medium to high levels of activity in temperate (European) climates.
