Tactical Combat Casualty Care patch
 

Canadian medical services in Afghanistan wear a Tactical Combat Casualty Care tablet. It reads TCCC, black on sand. It is worn on a brassard on the right shoulder.

As in anything Military - while there is supposed to be a "set-rule" sometimes there isn't. I have a photo of this badge/patch being worn on the LEFT - lower- upper arm on the velcro mounting position.

TCCC / MEDICAL patches
 

Just got back from the sand box and I'll offer the following. "TCCC" patches are worn by non medical personnel who have completed the Tactical Combat Casualty care course of ten dats duration. The course trains the individual soldier to recognize life threatening wounds / injuries and perform life saving interventions above and beyond any military first aid qualification.

Medical personnel employed in a medical treatment facility such as the one that exists in KAF wear a Cadpat AR red cross brassard while medical personnel employed outside the wire wear a "MEDICAL" patch similar in size to the "TCCC" version. Wearing a red and white cross in bad guy country is probaly not a good idea...

Weapons - since the Korean War, Canadian medics have been armed for self defense / protection of casualties.
