HHC 42nd Infantry Division

Headquarters and Headquarters Company (HHC), 42nd Infantry Division, known as the “Rainbow Division,” traces its origins to World War I, when it was formed in 1917 from National Guard units across the United States. HHC provided essential command, control, and administrative support to the division during major engagements in both World Wars, including the Meuse-Argonne Offensive and the liberation of Dachau concentration camp. After periods of inactivation, the unit was reactivated and has since participated in domestic support missions and overseas deployments, including Operation Iraqi Freedom. Today, HHC 42nd Infantry Division remains a vital element of the New York Army National Guard, continuing its legacy of leadership and service.
