It just seems that most of the troops were given two year recruitment papers (later amended to 18-months) and were these people considered to be useful by the RAF, RN and the British Army? Were they considered to be effective in combat situations?
Conscription was ended partly because it was no longer needed, having been a sort of hang over from WW2, and partly because the armed forces didn't like it. A vast amount of time energy and effort was used to turn mostly unwilling conscripts into members of an armed force that they would leave before their skills would be used. They were, however, certainly effective in Malaya, Egypt and Korea, and were of use in Cyprus.
