The PAM, also known as the Permanent Force (PF), was in effect Canada's standing army, consisting of one regular infantry regiment and two cavalry regiments up until 1914. The PAM did not participate directly in the First World War; Canada's military contribution was the creation of a separate field force called the Canadian Expeditionary Force (CEF) into which volunteers (and later conscripts) were inducted for war service. The CEF was disbanded after the war.
