 Navy reservists partnered with the Army and Air Force in a field exercise at Fort McCoy, Wisconsin, May 16th. More than 6,000 reservists participated in this year's combat support training exercise, or CSTX. The Navy built a functional 44-bed combat support hospital. The Army flew patients to and from the hospital using the HH-60 Blackhawk. The Air Force provided TRACES, a system that facilitates patient evacuation by air. Sailors also attended Northern Lights, an annual Navy reserve medical training exercise as part of CSTX. Northern Lights provided practical experience in the expeditionary medical facility environment. With the training sailors received, they will be capable of performing basic and tactical operations for worldwide deployment. Exercises like CSTX show how military medicine is a joint effort.
