Airman 1st Class Alexander Armitage, avionics technician in the 419th Aircraft Maintenance Squadron, dons mission oriented protective posture gear during an exercise Sept. 16, 2020, at Hill Air Force Base, Utah. The gear protects Airmen from chemical, biological, radiological, and nuclear agents that could be used in a contested environment.
