"And, when the platoon gets in trouble, it's not because somebody screwed up....
It's because it was on the training schedule"
+1 Like I said, mind game.
Everyone is afraid to fail. That's why they will make sure you do. Again and again. The only way to truly fail is to give up. Your muscles will fail. Your emotions will fail. And sometimes you'll be pretty sure your sanity has failed. They will make you squad leader just to smoke you when someone in your squad fucks up. You will watch people crack and you will see grown men cry like babies. Usually it's the guys who go in thinking they are tough and know it all. The guys who make it alright are the ones who take everything as it comes, keep their back straight, STFU and listen.
Other good things to know are don't volunteer information and when you hear an unusual question like "Who here has a driver's license?" or "Which one of you turds knows how to cook?" Let some other idiot answer that. Likely the one who runs his mouth ends up on KP or "driving" a wheelbarrow.
Edit: Oh yeah. And don't do impersonations of your drill instructor. They really hate that.
