Radio check
Firefighters from the 23rd Civil Engineer Squadron signal for a radio check prior to advancing on a fire during nighttime, live-fire training Jan. 10, 2017, at Moody Air Force Base, Ga. The training is an annual requirement for Moody AFB firefighters and is just one of the ways they stay ready to protect people, property and the environment from fires and disasters.
