Not much has been posted about the PCMR. The unit was a para-military group tasked with being the observers of unusual activity in the remote coastal and mountain areas of British Columbia. To ensure their status as combatants, they were issued armbands which could be worn on civilian clothing or military uniforms, a distinctive headdress and insignia.
A short explanation of the role and history of the unit can be found in this article
Pacific Coast Militia Rangers. In the linked pages, the dress regulations of the group are outlined.
The armband was the basic identifier for the PCMR. Doe anyone have a list of the PCMR companies?
