Gen. Mark Welsh became the Air Force’s 20th Chief of Staff during a ceremony at JB Andrews, Md., on Aug. 10. Air Force Secretary Michael Donley swore in Welsh at 11:56 a.m. US East Coast time. “Today, being sworn in as the Chief of Staff of the Air Force, I just feel humble,” Welsh told the assembled airmen and guests after assuming command. “No one has been more proud to be your Chief of Staff, and it’s about time I get to work.” Welsh replaced Gen. Norton Schwartz, who served as Chief of Staff since August 2008 and is retiring from the Air Force after 39 years in uniform.
