The 58th Infantry Brigade Combat Team was one of the primary units of the Maryland Army National Guard. It consisted of an infantry brigade combat team (IBCT) format of two infantry battalions, one light cavalry squadron, one towed artillery battalion, a brigade support battalion and a special troops battalion. It deployed overseas for combat service in the Iraq theater during the War on Terror in 2007. This is the brigade's first combat deployment, although some of its subordinate units served in prior wars.
