|First airborne organization to be activated under the United States Army's new ROAD ( Reorganization Objective Army Division) concept came into being on Okinawa in June 1963 when the 173rd Airborne Brigade was formed from elements of the 2nd Airborne Battle Group, 503rd Infantry, immediately upon the battle group's return from participation in Exercise "DHANARAJATA", the SEATO maneuver in Thailand, June 25, 1963 the 2nd Airborne Battle Group, 503rd Infantry, was inactivated. It had been on Okinawa three years following its designation in March, 1960 as the 2nd Airborne Battle Group, 503rd Infantry Combat team and its subsequent departure from the 82nd Airborne Division, Fort Bragg, North Carolina. Officers and troopers became part of the newly organized 173rd Airborne Brigade. Initial reorganization began in March, 1963, when Headquarters Company of the new brigade was formed. Activation of the brigade brings to implementation a new concept of today's Army:
Formation of a force augmented not only in manpower but in mobility and firepower as well. One thing remains unchanged, however, and that is the will to win and preserve the freedoms that are America's heritage and to do it in the "Airborne, all the Way" Spirit.
