Not sure what to tell you. When 3 PPCLI was assigned to the AMF in 2001/2002 we only wore the pin backed enamel shield in place of the command badge on our DEU's. Perhaps a cloth badge was used in the earlier days of the AMF for wear on the combat uniform. Keep in mind that many nations participated in the AMF and they each had their own version of the badge for wear on their uniforms. Also, I do know that various AMF badges and misc souvenirs were sold in some kit shops for the various units that rotated through their turn as the IRTF(L) (immediate reaction task force - land).
We wore them on the right upper sleeve. When I was in 1 RCR, we also wore the AMF metal badge on the left CF pocket and the Mobile Command badge on the right pocket. When we got the new DEU, we only wore the AMF badge on the right pocket.
