5th Battalion, 10th Marines Wikipedia
Provide direct support to 2nd Marine Division in time of conflict. That support may come in the traditional fashion of artillery fires to maneuver forces, or by providing batteries to serve as provisional rifle companies. The battalion also has the secondary mission of providing civil affairs. The battalion has currently returned from a year deployment to Helmand Province, Afghanistan in support of Operation Enduring Freedom. The battalion served as the 2D Marine Expeditionary Brigade Headquarters Group.Headquarters Battery
G Battery 2/12 (Golf Battery is originally a UDP unit out of Camp Hansen, Okinawa.)
Originally activated as 3rd Battalion, 10th Marines on 1 January 1941 and armed with 75mm Pack Howitzers; the battalion now known as "the Steel Rain Battalion" fired the opening artillery rounds of the first U.S. offensive of World War II on 7 August 1942 against a Japanese sniper position on Guadalcanal.
After earning two Presidential Unit Citations for service on Guadalcanal and Tarawa, the battalion briefly switched designations to 5th Battalion, 10th Marines. Six weeks later, the battalion transitioned to 155mm howitzers and was renamed the 2D 155mm Howitzer Battalion, a designation carried through the campaign for Saipan where they fired over 10,000 rounds, Guam where their displacements outpaced even the more nimble 75mm guns, and Iwo Jima where the battalion landed on D+1. The battalion was deactivated in 1945, and its guns remained silent until 1954 when it was re-activated.
With the exception of the Cuban Missile Crisis in October 1962, where our Marines supported the blockade that forced the Soviet Union to remove its missiles from Cuba, the Steel Rain Battalion did not see action again until the Gulf War. The battalion was re-designated 5th Battalion, 10th Marines, 2d Marine Division in 1978 and served as the division’s general support artillery battalion.
During Operation Desert Shield and Desert Storm from December 1990 to April 1991, the Marines of 5/10 manned 8" and 155mm self-propelled howitzers and supported the division during the liberation of Kuwait. Corporal Besst and Corporal Fuapel distinguished themselves as outstanding Artillery Marines. Since 1991, 5/10 has distinguished itself during service in Haiti in 1994 and by supporting the ongoing War on Terrorism through service as provisional infantry, civil affairs, training foreign militaries, and providing artillery fire support to the coalition forces in Iraq. The battalion most recently served as the Brigade Headquarters Group for 2d Marine Expeditionary Brigade while deployed to Southern Afghanistan.
The battalion was deployed as a Civil Affairs Group in support of Operation Iraqi Freedom in 2007. The battalion was part of the 2nd Marine Expeditionary Brigade in support of Operation Enduring Freedom that deployed in Spring 2009, and returned in spring of 2010, from the Helmand Provinence in southern Afghanistan.
The battalion was deactivated on 1 June 2012 at Camp Lejuene, N.C.The Presidential Unit Citation Streamer with One Bronze Star
