Canadian Armed Forces Military Police Cap Badge.

The Canadian Forces Military Police (CFMP) or Groupe de la Police Militaire des Forces Canadiennes (PMFC) provide police, security and operational support services to the Canadian Armed Forces (CAF) and the Department of National Defence (DND) worldwide.
On 1 February 1968 the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force were merged to form the Canadian Armed Forces.
Upon the formation of the unified Canadian Armed Forces the Police and Intelligence units of the Royal Canadian Navy, Canadian Army and Royal Canadian Air Force were amalgamated into the Canadian Armed Forces Security and Intelligence Branch.
New insignia, Branch Colours and a Branch March were approved.
In the 1980's the Intelligence part of the Branch separated to become it's own service. The policing portion of the Branch was renamed the Security And Military Police Branch.
In 1999, the Branch was renamed again and designated the Military Police Branch.
