I have seen the "new" MP IR shoulder patch on MPs (of which I am one) and have not seen anything authorizing this device? My question is A) Is this authorized and B) If so please POST or direct me to the regulation or instruction authorizing it.

I know the brassards are authorized because we have had them for years but the I have never seen anything authorizing a replacement.

I have also seen some medics wearing MED or MEDIC IR patches as well..

Any help would be appreciated.
