What is the Combat Lifesaving Course like?

Start with this link. One thing you won't learn is IV's. You will learn chest decompression and Nasal Pharyngeal Tube insertion, plus all kinds of other emergency life saving steps.

I used to teach this course. You learn basic life saving skills. Bandaging, splinting, airway management. How to set up and IV so that it's ready for the medic after he/she does the stick. You won't become a medic but you'll be able to recognize what kind and where wounds/injuries are so that you can brief the medic on what you've done and what still needs to be done. Combat Life Savers are of great value on the battle field. Especially if your medic becomes woulded or injured. Work within your scope of taught knowledge. Don't be out there trying to perform open heart surgery.

Depends where you go. I went to the Mystic in Fort McCoy and we learned quite a few different things. Honestly it wasn't hard but this question and answer is truly subjective. I love math and science and medical stuff. This course worked well for me.

Topics include use of nasopharyngeal tube, needle chest decompression, calculating surface area damage/burn over the body, how to apply a tourniquet, exfil a casualty, reporting a 9-line, etc.
