Airmen from the 30th Civil Engineer Squadron electric shop set out an Expeditionary Airfield Lighting System Nov. 5, 2019, at March Air Reserve Base, Calif. The 30th CES traveled to March ARB to use their Regional Training Site as they had the equipment needed for deployment readiness training. This 96-hour training event was part of the refreshed Prime Base Engineer Emergency Force program, where it is now required for CE Airmen to have similar training every 36 months.
