Cap Badge - 11th (BC) Canadian Garrison Regiment. Note the crown neatly removed from top. The photo shows the original version with a crown. Garrison Military Police The Canadian Garrison Regiment was authorised in July 1918 with a Battalion in each Military District. Garrison Battalions recruited men who were overage, had returned from overseas, or were unfit for duty overseas. Each Battalion had a Garrison Military Police detachment. Cap badges and collar badges worn by Garrison Military Police were likely the Maple Leaf pattern or that of the Canadian Garrison Regiment. A special cap badge was worn by members of No. 11 Garrison Battalion. Some Garrison Military Police were also appointed from NCOs of other regiments or corps. Garrison MPs so appointed wore the badges and insignia of their regiment. The Garrison Military Police brassard was worn by MPs on duty.
