Hello Marines, I have a few concerns about bootcamp that I wanted to clear up. I've heard that the cs gas you are put through is unbearable and clears your sinuses immediately I was wondering if that was true and if it is really that bad. I also was wondering if they will teach you how to swim if you don't know how because I can't swim. One more question, what do you have to do to get a perfect score on the pft?
