The CLS Course was only a guide for us when I was training my Team Mates years ago; meaning they were well up to speed when they got through. I knew as the lone Medic that I had to instill the skills necessary for them to take care of me if I needed help.
You'd be very surprised at the level of cross-training we go through. No man is an Island on a Team. One of the best trauma clinic's I saw ran was from an 18C.
