Staff Sgt. Justin Piercefield, 72nd Security Forces Combat Arms instructor, shows Air Force recruit Levi Maxwell how to properly position himself on the M2 machine gun during a weapons display portion of the Delayed Enlistment Program Call Apr. 8. The 72nd SFS worked with the 349th Recruiting Squadron to have 15 recruits learn more about the security forces career field. The military working dogs section, investigations, combat arms and training sections demonstrated their respective areas during the event, giving the recruits, some of whom haven't yet selected a career field, a better insight into this one.
