Marauders at typhoons?

I know ive heard someone talk about this somewhere, i thought it was here, but someone said they trained at typhoons, and im not sure how this would be done on a marauder, but i'd like to know if it's an option

Edit: Sorry once again on nibness, i see the training refrence has it as good exp for 100+, i still would like to know how this is done
I'd delete the thread if i knew how :x
