 What if your corpsman goes down? Then who's gonna who's gonna save him in case he can't aid to itself? I'm here because a marine saved my life when I was in Afghanistan We were in an IED explosion and I was unable to treat myself So one of my marines that had been to the CLS course he saved my life Combat lifesaver is a three-day course and it consists of instruction hands-on portions, so that's where the students, you know, use tourniquets they treat simulated injuries on each other and on mannequins and then we have the last day our final exercise where the students take everything that they learned over the previous couple of days and They apply it to be able to save someone else's life
