 So, this is the first of the 170 seconds combat lifesaver course. We have members of Alpha Troop and Bravo Troop up here today to get newly certified in the program, tourniquet application and wound packing and wrapping of trauma injuries, and airway management so that included needle decompression of the chest, application of the nasal pharyngeal airway, bagging or assisting the breathing of the patient, patient wrapping and packaging so hypothermia management and putting them on to an actual litter for transport. It's a requirement for us to have a certain number of people within the formation to assist the medics in providing that first roll of care.
