The 2nd Infantry Brigade Combat Team is a unit of the Pennsylvania Army National Guard’s 28th Infantry Division. 2nd Brigade’s headquarters is in Washington, Pennsylvania, and the brigade also contains units from Ohio and Maryland.
Headquarters, 2nd Infantry Brigade Combat Team was organized in July, 1872 as a company called the Washington Guards. In November, 1873 the company was formally incorporated into the Pennsylvania National Guard as Company H, 10th Pennsylvania Infantry Regiment.
Company H was mobilized for the Spanish–American War from 1898 to 1899 and served in the Philippines. In 1916 the company was federalized for service on the Mexico–United States border during the Pancho Villa Expedition.
In 1917 Company H merged with Company H, 3rd Infantry Regiment, and the new unit was designated Company H, 110th Infantry Regiment. From August, 1917 to June, 1920 the 110th Infantry was mobilized for service in France during World War I.
Company H, 110th Infantry was inducted into federal service for World War II in February, 1942. It served with the 28th Infantry Division in the European Theater, and was demobilized in October, 1945.
In September, 1950 Company H was activated for service during the Korean War, and remained mobilized in West Germany until June, 1954.
Company H was re-designated Company C, 1st Battle Group, 110th Infantry as part of a 1959 reorganization.
In 1963 Company C was combined with Headquarters, 1st Battle Group, and the new unit was designated Headquarters and Headquarters Company, 2nd Brigade, 28th Infantry Division.
In 1968 the 2nd Brigade Headquarters was reorganized as the 689th Military Police Company. In the early 1970s, another reorganization led to the creation of the 408th General Supply Company.
