Airman 1st Class Jacob Westafer, 319th Logistics Readiness Squadron fire truck maintenance apprentice, returns a tool to his work station August 28, 2018, on Grand Forks Air Force Base, North Dakota. Westafer attended roughly five months of technical training in order to learn about miscellaneous tools, vehicular pieces and operations, but he says a majority of what he knows now is due to his on-the-job training.
