Missions include general support, counter-battery fire, and suppression of enemy air defense systems. The M110 was exported to a number of countries. General CharacteristicsAccording to the operator's manual, the M110's typical rate of fire was three rounds per two minutes when operated at maximum speed, and one round per two minutes with sustained fire. The M110 featured a hydraulically operated rammer to automatically chamber the 200+ pound projectile. These rammers were prone to breakdown and generally slowed operation of the gun, because the rammers required crews to completely lower the massive barrel before using it. Highly trained and motivated U.S. Army crews could achieve two to four rounds per minute by using the hand-operated manual rammer, which was essentially a heavy steel pole with a hard rubber pad on one end. Using the manual rammer was physically demanding, but crews were not required to lower the barrels nearly as much as with the hydraulic rammer.{{Citation needed|date=October 2014}} The M110's range varied from 16,800 meters to approximately 25,000 meters when firing standard projectiles, and up to 30,000 meters when firing rocket-assisted projectiles. HistoryThe M110 howitzer first entered service with the U.S. Army in 1963 and was used in the Vietnam War by the United States Army. Later versions were used in Operation Desert Shield and Operation Desert Storm by Romeo Battery 5th Battalion 10th Marines, and the British Army. In 1977 the upgraded M110A1 entered service, featuring a longer M201 series barrel which gave increased range. The M110A2 is the latest version with a double muzzle brake, in contrast to the earlier A1 version which had a plain muzzle. The 2nd Battalion 18th Field Artillery and the 5th Battalion 18th Field Artillery served in Desert Storm with the M110A2 Howitzer, as well as the 142d Field Artillery Brigade (Arkansas Army National Guard), and 1st BN 181 Field Artillery (Tennessee Army National Guard). Most of the U.S. Army and USMC relied on the M109 series 155 millimeter gun systems during this conflict; sending remaining M110s to reserve or National Guard units. These units then took possession of M109s as they returned from service in the Gulf. M110s were still in service with the 3/92 FA (USAR) and running fire missions at Camp Atterbury as late as the summer of 1994.[2] The gun system has been retired from U.S. Army service; howitzers above 155 mm caliber are no longer considered to be practical, as technology has closed the range and firepower gap,{{citation needed|date=September 2014}} and heavier weapon systems require more resources to operate. Gun barrels from retired M110s were initially used as the outer casing in the manufacture of the GBU-28 bunker buster bomb. The M110A2s were made from refitted M110s or M107 175 mm SP guns (Hunnicutt). At the end of the Cold War under U.S. Division Plan 86, all armored and mechanized infantry divisions included a battalion of heavy artillery that included two batteries of M110A2 8" SP howitzers with six guns each for a total of 12 guns, plus one battery of nine MLRS rocket artillery.{{citation needed|date=August 2017}} Projectiles
