An Officer Cadet Training Unit (OCTU) took either civilians or other ranks and trained them to be officers. The majority of infantry officers would have been trained through the Royal Military College, Sandhurst, which became the Royal Military Academy in 1947. However, during wartime, Sandhurst did not have the capacity to train all of the officers required. Therefore, specialist OCTUs were established and supplied officers to distinct arms of service, including machine gun battalions as a separate specialism to the infantry.


Second World War

An OCTU at the outbreak of the Second World War was established with a headquarters element, a headquarters company, one recruit company and four training companies, each with three platoons. The output of the OCTU was 95 trained cadets per month. They received 100 each month (and expected a loss of 5). The cadets would spend four weeks in the recruit company and then 16 weeks in one of the training companies.
