Officers of the Army Cadet Force who are on the strength of cadet units are dealt with in the same way as officers of the Home Guard. They receive no pay, but rations and compensation for loss of earnings whilst attending courses and attachments, and certain free services including free travel in certain circumstances. Officers of the Sea Cadet Corps and of the Air Training Corps are treated somewhat differently when they attend approved camps or courses. They are in general given the pay of their substantive rank for a limited period in addition to free accommodation and rations.
