War. The Second Boer War saw more than 8,000 volunteers raised for service in South Africa, from 82 different militia units. From 1875 to 1904, the officer heading the Canadian Militia was the General Officer Commanding the Canadian Militia (GOC), a position legally required to be held by an officer of the British Army. However, serious differences in opinion over divisions of responsibilities between the civil and military branches of the Militia Department would see the post virtually abolished under the Militia Act of 1904. The office of the GOC was replaced by the Militia Council. The six member council included the Minister of Militia serving as the council's president, another civilian member, typically the Deputy Minister of Militia, and four members drawn from the Canadian military, the Chief of General Staff, the Adjutant General, the Quartermaster General, and the Master General of the Ordnance. Although modelled after the British Army Council, the Militia Council was purely an advisory body, with the Minister holding supreme authority over it; and the Chief of General Staff becoming the premier military member of the council. The militia also saw several administrative reforms instituted in the early 1900s, with the establishment of the Canadian Army Service Corps in 1901; the Canadian Military Engineers, the Ordnance Stores Corps, and the Signalling Corps in 1903; and the Permanent Active Militia Medical Corps in 1904. World Wars and Interwar period During World War I, the militia was not mobilized, with Canadians serving overseas enlisting with the Canadian Expeditionary Force (CEF), a separate military field force managed by the Ministry of Overseas Military Forces. As World War I drew to a close and the CEF expected to disband, the Otter Commission was launched in an effort to reorganize the Canadian militia. The Commission proposed that PAM field a force of six infantry divisions, one cavalry division, supplemented by personnel from NPAM. Additionally, the Otter Commission saw links of perpetuation created between CEF and Canadian Militia units; permitting militia units to perpetuate the battle honours earned by CEF units disbanded after the First World War. Improvements to both PAM's and NPAM's officer corps were undertaken in the 1930s, with PAM officers directing officer cadets through courses such as the "Advanced Militia Staff Course," beginning in 1935. As a result, the Militia fielded a much larger officer corps in 1939, when compared to 1914; with the Canadian Militia fielded approximately
