Really? Where did you do it and who run it? I did the instructor course at WG about 2 years ago and we were told "there are no more assistant courses" and we were given a bag of CDs with powerpoints on them and told to produce our own assistants.
No, but that looks like something thats been accredited by your Bde area. A CBRNI is qualled to teach at WB as much as s/he is in Strensall. Ask Bde what plans are in place to fam people on the GSR in your area. I've got a feeling that reg units are going to get famming first, but you never know.
Oh, and if you get any info about it, let us know?
