The 1st Infantry Brigade (nicknamed "Mountaineers") is a light infantry brigade of the Shenandoahan Army National Guard. Though the brigade has formations located at various facilities throughout southern and southeastern Shenandoah, it is headquartered at Fort Winfield, Cumberland, near the city of Canaan.
As the oldest Shenandoahan Army National Guard infantry formation, some iteration of the 1st Infantry Brigade has participated in every combat action undertaken by the Shenandoahan Commonwealth since its creation in 1924. The present day organization of the brigade was established in March of 1999, with all active divisions of the Shenandoahan Army National Guard were deactivated and dispersed into brigade sized elements to allow more tactical flexibility in deployment along the Shenandoahan-Copperhead border. Although there are no active divisions within the Shenandoahan Army National Guard, units are organized so as to allow for the formation of ad hoc divisions as needed., referred to as a Combat Force. The current iteration of the 1st Infantry Brigade is part of First Combat Force Command under the command of Major General Wilson P. Terry. Other units included in the 1st CFC is the 2th Field Artillery Regiment, 44th Engineering Regiment, and the 15th Cavalry Regiment, among others.
