Following the deactivation of the 2d Battalion, 110th Field Artillery Regiment, the 110th IO FSB was given the honor to carry the 2d Battalion 110th Field Artillery lineage which dates back to World War I. The 110th IO FSB was designed to provide trained, deployable, culturally aware, and regionally focused information operations teams to perform tactical strategic-theater IO tasks.
The unit's higher operational headquarters appears to be the 56th Theater Information Operations Group, Washington Army National Guard. Led by Army Lt. Col. Richard Amott, 110th IO commander, and Army Command Sgt. Maj. Kimberly Mendez, 110th IO command sergeant major, within the state of Maryland, as of Nov. 1, 2011, the battalion has been reorganized from under the 29th Combat Aviation Brigade in Edgewood, Md. to the 58th Battlefield Surveillance Brigade in Towson, Md.
The mission of the 110th IO is to conduct tactical through strategic level Information Operations in support of global military operations by training and deploying culturally aware and regionally focused IO teams IOT defeat adversary information operations and gain information superiority in the information environment; or, be prepared to conduct limited, approved IO tasks in support of state and local authorities during governor-declared state emergencies and provide support to restore civil order, as directed by the governor and the adjutant general.
In support of its federal mission, the 110th IO FSB has deployed many field support team (FST) since its activation, to multiple areas, providing IO operations to the active duty force. The battalion’s motto, “Informatio Dominatus Orbis Terrarum” meaning “Information Dominates the World” reaffirms the full spectrum of strategic planning across a range of military operations.
