Editing M110 howitzer (section)

==History==
The 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 the [[Gulf War]] - [[Gulf War#Operation Desert Shield|Operation Desert Shield]] and [[Operation Desert Storm]] by Tango Battery [[5th Battalion 11th Marines]], and the [[British Army]]'s [[32nd Regiment Royal Artillery]].<ref>[https://www.youtube.com/watch?v=dJfcVG8mu_s 32 Regiment RA in action - Gulf War 1991]</ref>

In 1977 the upgraded M110A1 entered service, featuring a longer M201 series barrel which gave it an increased range. The final version, the M110A2, added a double [[muzzle brake]]. The M110A2s were made from refitted M110s or [[M107 self-propelled gun|M107 175&nbsp;mm self-propelled guns]].<ref>(Hunnicutt)</ref> The 2nd Battalion 18th Field Artillery (U.S. Army), which inactivated in 1994 at [[Fort Sill]], Oklahoma, and the 5th Battalion 18th Field Artillery served in Desert Storm with the M110A2, as did the 142nd Field Artillery Brigade ([[Arkansas Army National Guard]]) and 1st Battalion 181st Field Artillery ([[Tennessee Army National Guard]]). Most of the U.S. Army and Marine Corps relied on [[M109 howitzer|M109 series 155-millimeter howitzer]] systems during this conflict, sending remaining M110s to reserve or National Guard units. These units then took possession of M109s as they returned from combat operations. M110s were still in service with the 3rd Battalion 92nd Field Artillery (US Army Reserve) and running fire missions at [[Camp Atterbury]] as late as the summer of 1994.<ref name="youtube-gulf-war-1991">[https://www.youtube.com/watch?v=dJfcVG8mu_s UK M110 Artillery in action Gulf War 1991]</ref>

The howitzer has been retired from U.S. Army service, replaced by the [[M270 multiple launch rocket system]].

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 SP howitzers with six guns each for a total of 12 guns, plus one battery of nine [[M270 multiple launch rocket system|M270s]].{{citation needed|date=August 2017}}

Israel used M110s along with M107s during the [[Yom Kippur War]] against Egyptian and Syrian forces. Later, in 1982, Israel used M110 systems against the [[Palestine Liberation Organization]] and their Lebanese allies with deadly effect during the [[Siege of Beirut]] as part of [[Operation Peace for Galilee]].{{citation needed|date=February 2022}}

Iran used its M110s during its offensives against Iraq in the [[Iran–Iraq War]].{{citation needed|date=February 2022}}

The [[Turkish Armed Forces]] have used M110A2 systems against the [[Kurdistan Workers' Party]] since the 1990s, as well as in the [[Turkish occupation of northern Syria|Turkish military intervention in Syria]], mainly against the [[People's Protection Units]].{{citation needed|date=February 2022}}
