Peter Gersten, U.S. Air Force Warfare Center commander, Nellis Air Force Base, Nev., speaks to race attendees before issuing the oath of enlistment for Air Force recruits and prior to the start of the "Gander Outdoors 400" Monster Energy NASCAR Cup Series race Oct. 7, 2018, at Dover International Speedway in Dover, Del. Forty-two recruits joined the U.S. Air Force, Delaware National Guard and Air National Guard through the Delayed Entry Program. Under the DEP, individuals going onto active duty, enlist first into the DEP. This is an actual enlistment into the inactive Reserves, with an agreement to report for active duty to attend basic military training at a specific time in the future.
