HHC 3:3 Infantry

Headquarters and Headquarters Company, 3rd Battalion, 3rd Infantry Regiment (HHC 3/3 Infantry), traces its lineage to the historic 3rd Infantry Regiment, known as "The Old Guard," which was first constituted in 1784. Over the centuries, the 3rd Battalion and its HHC have served in numerous conflicts, including the Civil War, World Wars I and II, and more recent operations. As part of The Old Guard, HHC 3/3 Infantry has played a vital role in ceremonial duties in the National Capital Region, honor funerals at Arlington National Cemetery, and security missions. Today, the unit continues its dual mission of ceremonial excellence and readiness to respond to defense requirements.
