U.S. Marine Lt. Col. Sean Riordan, 1st Battalion, 3rd Marine Regiment battalion commander, bids farewell to Garmsir during a transfer of authority ceremony at Forward Operating Base Delhi, Nov. 17. Riordan is a native of Montclair, Va. ‘The Lava Dogs,’ 1/3, transferred authority of Garmsir to ‘America’s Battalion,’ 3/3. During their seven-month deployment the Marines and sailors of 1/3 have helped Garmsir progress toward transitioning authority of the district to Afghan security forces and the Afghan government. The Lava Dogs, who arrived here mid-April, began the journey home to Marine Corps Base Hawaii in early November.
