B Battery 5th 77th FA

B Battery, 5th Battalion, 77th Field Artillery (B/5-77 FA) traces its lineage to the historic 77th Field Artillery Regiment, first constituted in 1916. Throughout its service, B Battery has supported various U.S. Army divisions, providing critical artillery fire support in major conflicts, including Vietnam, where the 5th Battalion was attached to the 1st Cavalry Division (Airmobile). In Vietnam, B Battery earned distinction for its mobility and effectiveness in supporting infantry operations, often deploying by helicopter to provide rapid, close fire support. After Vietnam, the unit continued to serve in various capacities during the Cold War, adapting to evolving military technologies and doctrines before eventual inactivation as part of Army restructuring.
