GUATEMALA CITY, Guatemala -- Senior Airman Mason Cairns , a weather specialist with 612th Air Base Squadron at Soto Cano Air Base, Honduras, relays weather updates to the forward deployed command staff during a medical readiness training exercise here Nov. 30. Weather forecasts are necessary to mission planning, both for air and ground transportation planning, because commanders must make decisions based on possible adverse atmospheric conditions. Airman Cairns was part of a three-man team working communications and weather from the airport here. (U.S. Air Force photo/Tech. Sgt. Benjamin Rojek)
