 So, the ultimate goal for this training is they can take people's lives. A mass cow provides a high stress level for both the ground medics and the flight medics and basically it's chaos and we need to expose them to multiple patients so they can stay calm under pressure. The beginning of the mass cow is obviously moulaging the patients. My personal philosophy on the moulage is just providing the actual, the visuals, the senses to get the medics to I guess act like or feel like it's real, giving them some real world battlefield injuries and then we set them up at a site and have them attacked. The main objective here is to provide realistic scenarios for both the ground medics and the flight medics and then the ground medics triage and then transport them to a CCP or a casualty collection point where they can get an accurate count on the wounded and then they call in a nine line for medical evacuation. As the helicopters are inbound, we communicate, usually in the nine line we give them the color of smoke so they can identify that, hey this is the actual LZ and they can confirm it with the color of smoke. I feel every medic from a PFC to a certain first class benefits from any sort of medical training and it's just exposure, the more exposure that they have in training the better they'll act in a real casualty.
