U.S. Air Force Senior Airman Joseph Umipeg, 721st Aircraft Maintenance Squadron crew chief, tests communication cables on a U.S. Air Force C-17 Globemaster III aircraft while dawning full Mission Oriented Protective Posture (MOPP) 4 gear, during exercise Nodal Lightning 20-2 at Ramstein Air Base, Germany, Oct. 21, 2020. Prior to lifting the aircraft to simulate replacing a wheel, Umipeg ensured that all the 721st AMXS Airmen could communicate the mission objectives. Nodal Lighting 20-2’s objective was to execute live events focused on executing the mission in a contested, degraded, and/or operationally limited environment.
