U.S. Air Force Airmen assigned to the 28th Civil Engineer Squadron participate in a litter carry exercise during the Prime Base Engineer Emergency Force, also referred to as BEEF, Challenge at Ellsworth Air Force Base, S.D. Sept. 22, 2022. The Prime BEEF Challenge is a physical and mental readiness challenge that tests every engineer’s capability to operate while under extreme stress. This means that any disaster that occurs here, the 28th Bomb Wing has a civil engineer unit fully prepared and capable to respond and resolve the situation.
