Doesn't matter what colour uniform you wear in health services. It's really purple with a distinct undertone of green to it. You will go where you are needed and given that the Reg F Fd Ambs need med techs, its very likely that you will end up there. Hmm HMCS 1 Fd Amb, sounds interesting. Why not HMCS 1 Fd Amb Medical Sqn just to round it out? ;D
