:threat: OK.. Let's clear this up for everybody! I have the accurate information, since I currently instruct at CFSEME Regimental Company!
OFFICIALLY, a student coming to CFSEME will not wear the EME cap badge until it has been presented to them (QL3's only). This happens at Regimental Company upon completion and graduation from their QL3 CET (Common EME Training) course. Anybody that belongs to EME, SHOULD NOT be wearing the EME cap badge at all while at PRETC, however it IS happening. So to summarize, once a QL3 has completed the CET at Regimental Company CFSEME and has been presented the cap badge, then... and only then will they wear it on their berets. I hope this clears up this whole topic for all of you.
On another side topic, students are also supposed to receive "The Green Monster" once they begin their training within CFSEME (also usually at Regimental Company). The Green Monster is the EME Branch's manner in which the QL3 trainees (Apprentices) are identified within the school environment. It has a long-standing tradition within the EME Branch, a tradition that has in the past few years been re-introduced. The "Green Monster" is a dark green strip of ribbon/fabric that is sewn onto the no-hook Private (Apprentice) slip-on. The green stripe resembles that of a Second-Lieutenant's bar, however the colour distinguishes it from all other CADPAT clothing. Currently, there is no supply of the CADPAT EME Insignia tags for the slip-ons available, so the issuing of "The Green Monster" has halted for the time being. At least until the stock is received by the CF Supply sections. On my promotion to MCpl, I had to take my Cpl slip-ons in to get my new MCpl slip-ons made, using the EME tags from my Cpl's. So, there you all are... more than you probably really wanted to know... and then some!
