180727-N-KF478-634 CORPUS CHRISTI, Texas (July 27, 2018) Hospital Corpsman 2nd Class John Hensen, from Metuchen, New Jersey, and a tactical combat casualty care (TCCC) instructor demonstrate the application of an occlusive dressing to create a firm seal over a wound in the torso region so that air doesn’t enter the chest cavity during a TCCC course at Naval Health Clinic Corpus Christi, Texas. Through the TCCC program, corpsmen will gain the skills, mind-set and knowledge to perform with confidence, and will improve their ability to limit preventable deaths on the battlefield.
