HMH-361 First to Use ‘cool,’ New Modification in Combat

09 – 29 – 2010 / HMH-361 is the first squadron to use the Micro-climate Cooling Unit System (MCUS) vest in a combat zone: the MCUS, made of a thin material laced with hoses that carry cool liquid, straps on with Velcro over the shoulders and sides of the vest. It circulates cold liquid around crew chiefs’ and pilots’ bodies during flight to reduce their core temperatures. The new vest raises energy levels and helps keep the crew and pilots focused, while flying by keeping them cool during extended missions in high temperatures.
