The implementation of officer SCODs will occur in phases for Regular Air Force, Air Force Reserve, and Air National Guard Airmen. The first SCOD for officers will begin with first and second lieutenants on Oct. 31, 2022, followed by colonels on Feb. 28, 2023, lieutenant colonels and majors on May 31, 2023, and captains on Aug. 31, 2023. All SCODs will repeat annually thereafter. Those in a promotion-select status will align their OPR with the SCOD of their selected grade. (U.S. Air Force graphic by Staff Sgt. Kiana Pearson)
