Sean J. Byrne was named Assistant Administrator for Human Capital in December 2010. He joins TSA after a distinguished, 36-year career in the U.S. Army. A Major General, he most recently served as Commanding General of the Army Human Resources Command (HRC) at Fort Knox, Kentucky, where he was responsible for Army-wide human capital programs.
Byrne’s military service includes five command postings at both international and national locations, and staff assignments at the Pentagon and the White House, where he served as the Vice President’s Military Assistant, and later as the President’s Military Aide.

In 2005, under the Base Realignment and Closure program, Congress directed the Army to consolidate and move the HRC’s three major operational elements to Fort Knox. Byrne led the HRC’s reorganization, transformation, and movement. The HRC is responsible for providing a full range of human capital support to a population of nearly 1.2 million Active Duty, Reserve, and National Guard service members and retirees.
Byrne has led workforces ranging in size from 100 to nearly 5,000, and in support of populations ranging from 4,000 to more than 1.2 million soldiers and civil servants.
