M102 105mm Howitzer

First introduced during the Vietnam War, the M102 was the light-towed 105 mm howitzer used by the United States Army in the Vietnam War and the First Gulf War. It fires a variety of conventional munitions and traverses rapidly through 360 degrees. M102s can be dropped by parachute or transported by utility helicopters for normal movement or air assault operations. The M102 is no longer in use by the United States Army, having been replaced by the M119. It is, however, still in use by the National Guard. It is also used on the USAF’s Lockheed AC-130 gunship.
