They don't expect you to already have knowledge of this and will teach you all you need to know there.
Interestingly enough, if you go onto a RMQ course, that also qualifies you to take WHT's. Which is a little alarming when you are a SAA instructor and you see guys who have been running a range for 20 years taking a WHT that could've come out of an SLR manual. But this is the exception and not the rule!
