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. The howitzer has been retired from U.S. Army service having been replaced by the M270 Multiple Launch Rocket System. The M110A2s were made from refitted M110s or M107 175 mm SP guns 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 rocket artillery. Israel used M110s along with M107s during Yom Kippur War against Egyptian and Syrian forces. Again in 1982 Operation Peace for Galilee, Israel used M110 systems against PLO and Lebanese allies with deadly effect during Siege of Beirut. Iran used its M110s during Iran–Iraq War against Iraqi forces during its offensives against Iraq. Turkish Armed Forces have used M110A2 systems against Kurdistan Workers' Party since the 1990s and during Turkish military intervention in Syria, mainly against People's Protection Units.
