Anyone who thinks you can go through BUDS/RASP/RIP/Q-Course/whatever injured and "fight through it" is a delusional fanboy. The reality is that it has very little to do with willpower and everything to do with your physical condition before the course and your genetic potential.
If you get hurt, you are out, and you are checking gates for 12 hours a day or go regular infantry. Yes, there are second chances, but that's another story.
