Aerial Rocket Artillery

Although sometimes used as a generic term for any armed helicopters, the term Aerial Rocket Artillery (abbreviated ARA, and sometimes just called Aerial Artillery) refers specifically to the armed helicopter units which were organic to the division artillery of the United States Army’s two airmobile divisions during the Vietnam War. The 2nd Battalion, 20th Artillery, 1st Cavalry Division and the 4th Battalion, 77th Artillery, 101st Airborne Division, along with Battery F, 79th Artillery, 1st Cavalry Division, were the only true ARA units that ever existed.[1]
