Well that doesn't make much sense. There's more injuries in many of the "official" CF sports than Muay Thai. Badminton (85% of elite badminton players are sidelined at some point due to an injury every year), Soccer, and Hockey both have a higher injury rate for sure, and isn't there a big Muay Thai thing at CFB Petawawa? Not to mention Tae Kwon Doe is an official CF sport... Seems pretty stupid to me.
I'm confident I'll get it approved and if not I'll go ahead and train in it anyway. I have no intentions in competing, I just want it in case there's ever a situation that requires it, plus it's hella fun and a good workout.
