History
The Aviation Brigade traces its heritage to 1 June 1959 with the activation of the 28th Aviation Company at the Capital City Airport, New Cumberland, Pennsylvania. The unit was reorganized as the 28th Aviation Battalion on 1 April 1963 and later relocated to 18th and Herr Streets (1976) and 21st and Herr Streets (1980) in Harrisburg, Pennsylvania. On 1 October 1986, the Aviation Brigade was organized under the Army of Excellence (AOE) design. Station relocation to the World War II barracks in area 2, Fort Indiantown Gap, occurred on 1 May 1992 for HHC, Aviation Brigade, and Detachment 1, HHT, Troops C and D (Air), 1st Squadron, 104th Cavalry, ending 33 years of service in the Harrisburg area. As of mid-1999, the brigade operated 86 Bell UH-1 Iroquois "Huey" and Bell AH-1 Cobra helicopters, as well as a supporting element of 27 M1 Abrams tanks and other ground combat equipment. Although training in the brigade is focused on possible employment in time of war, its soldiers are frequently called on to rescue endangered citizens and perform other emergency missions across the state. 2009 Iraq deployment
