M109A6 Paladin Howitzers from U.S. Army conduct call for fire missions during Exercise Eager Lion 2016 in the Hashemite Kingdom of Jordan.
The M109 is an American 155mm self-propelled howitzer, first introduced in the early 1960s. It has been upgraded a number of times, most recently to the M109A7. The M109 family is the most common western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions.
The M109A6 Paladin needs only a crew of four: the commander, driver, gunner and an ammunition loader.
