I never picked up SGT due to being a smart ass and hating my c/o then almost got in the reserves but managed to f that up , but we will not talk about that! and actually corey I think you are right and i am wrong , man I am losing my terminolgy here , just the other day i couldnt remember SOI (school of Infantry) and I 've been told it is MCT now (Marine Combat Training) . Acroynms and the Corp(s) they love em! put the S on for you gunny , but spelling and saying are different read as Corps and people think I'm talking about stiffs!
