After World War II, but before the unification of the Royal Canadian Navy (RCN), the Canadian Army and the Royal Canadian Air Force (RCAF), the security and police functions were conducted quite differently by the three Services. The Army divided the responsibility for security and security incidents between the Canadian Intelligence Corps (C Int C) and C Pro C and field inquiries were conducted by the Security Sections of the C Int C. The police functions of the C Pro C involved the provision and supervision of guards, the operation of Service Detention barracks and investigation of service and criminal offences. The Air Force Police (AFP) had the dual responsibility of performing both police and security duties and were under the command of the base on which they served.
