If you fail any land nav event, you are on mando remedial until you pass two land nav events in a row...and it is mando, you will be there or be UA. And remedial land nav is on Saturdays of course. You don't want to be there, because at TBS you need the weekends to unwind. If you fail a land nav final, you will get a 60% for a grade when you eventually pass it, no matter what you score on remedial. This sucks, because land nav is a huge chunk of your grade. I never failed a single land nav event until the day land nav exam, and then missed it by one box..got a 60%. Land nav sucks in Quantico in the summer, sometimes you just get a crappy card and you get boxes in really tough areas. If you are completely abysmal at land nav and can't ever even come close to passing, the possibility exists that you will be rolled to the next company, but from my experience, the SPC's and instructors want you to pass and will make sure you do. Have fun.
