The 48th Infantry Brigade Combat Team (INF BCT) ("Macon Volunteers") is a modular infantry brigade of the Georgia Army National Guard. One of the oldest units in U.S. Army history, the lineage of the 48th Infantry Brigade can be traced back to 1825. It is one of few units in the US military that also saw service as a unit of the Confederate States of America during the American Civil War. Today, the 48th INF BCT is part of the U.S. Army's "Associated Units" program where it's aligned under the 3rd Infantry Division, a combined arms (armor, mechanized, and light infantry) combat maneuver unit of the Regular Army.

The 48th Infantry Brigade Combat Team was originally organized on 23 April 1825, at Macon, Georgia as the "Macon Volunteers, Georgia Volunteer Militia". It mustered into Federal service on 18 February 1836, at Picolata, Florida, as "Captain Seymor's Company, 1st Battalion Georgia Volunteers".

The unit was brought into Confederate service on 20 April 1861 at Macon, and was reorganized and redesignated on 22 April 1861 as Company D, 2nd Battalion, Georgia Infantry. Surrendered 9 April 1865 at Appomattox, Virginia.

It reorganized on 11 April 1872 as the Macon Volunteers, and reorganized and redesignated 15 June 1874 as Company B, 2nd Battalion. It reorganized and redesignated on 23 January 1891 as Company B, 2nd Infantry Regiment. Mustered into federal service 11–14 May 1898 at Griffin, Georgia as Company F, 1st Georgia Volunteer Infantry; and mustered out of service on 18 November 1898 at Macon, Georgia and resumed state status as Company B, 2nd Infantry Regiment. The unit was redesignated on 21 December 1899, as Georgia State Troopers; and on 1 October 1905 as the Georgia National Guard. The unit was drafted into federal service in August 1917 as Company B, 151st Machine Gun Battalion, an element of the 42nd Division. It demobilized in May 1919 at Camp Gordon, Georgia.
