 TCCC is Tactical Combat Casualty Care. Tactical Combat Casualty Care is being used to replace self-made buddy care, the old system the Air Force used to train people to save lives. Tactical Combat Casualty Care is broken down into four tiers. The first tier is all-service member, which is a eight-hour class, which is meant for service members that aren't in a medical building, aren't in a medical profession. Second tier is the combat lifesavers course, which is a 40-hour class, which is meant for healthcare professionals that aren't necessarily healthcare providers. Third tier is for combat medics, combat corpsmen, or professions or members in medical professions who can provide more care. The fourth tier is for medical providers, such as doctors, people on that level, which can provide higher echelon care. TCCC is a more historical-driven training, which is current with the times it is replacing the old version of self-made buddy care with better tactics, better techniques based on historical gathered data. Service members taking Tactical Combat Casualty Care need this training to save lives, whether on the battlefield or the BX. It provides them with the hands-op training and knowledge to save a life at any time anywhere. Tactical Combat Casualty Care is a course you have to take. Through your UTM, they'll sign you up. You're going to deploy. It's got to be within 12 months of your deployment. Every three years take a refresher course on Tactical Combat Casualty Care and your unit will push you in. What I learned in the TCCC training was the different levels of, I guess you could say, first response. In this particular course was the combat lifesaver, so we're level two. One of the things that I learned that was above the self-made buddy care method was, in fact, for example, needle decompressions. That was kind of new. It's very intimidating for some because you're literally sticking a needle into someone's chest. To be able to learn exactly where to do it and how to do it, it's a very exciting experience. Here, too, is all your medical AFSCs and MOSs, depending on the branch you're in. If you have a medical job, you're going to be a level two, which is your combat lifesaver. The importance is it's going to save lives. By knowing how to save lives and be a first responder, you can effectively change the battlefield.
