3rd Battalion, 11th Marines is an artillery battalion of the United States Marine Corps assigned to the 11th Marine Regiment and 1st Marine Division, based at Camp Pendleton, California. The battalion provides fire support, counterfire, and combined arms coordination for Marine Expeditionary Units, amphibious task forces, and joint operations, supporting tactical maneuver by delivering indirect fires and integrating with aviation and armored elements.

History

3rd Battalion, 11th Marines traces its origins to World War II activations on Camp Elliott, participating in campaigns that connected with the Guadalcanal Campaign, Battle of Okinawa, and later Cold War-era deployments tied to Operation Desert Storm, Operation Iraqi Freedom, and Operation Enduring Freedom. During World War II the battalion supported assault landings alongside the 1st Marine Division and collaborated with units such as the 2nd Marine Division and 5th Marine Regiment in campaign planning and logistics. In the postwar period the battalion rotated through garrison assignments at Camp Pendleton and expeditionary deployments with Marine Expeditionary Unit amphibious ready groups, engaging in joint training with United States Navy amphibious squadrons and interoperability exercises with United States Army artillery formations. Recent history includes stability operations coordinated with NATO partners, security cooperation with Japan Self-Defense Forces and Australian Defence Force units, and participation in multinational exercises linked to the Pacific Command area of responsibility.

Mission and Organization

The battalion's mission aligns with doctrinal tasks found in Marine Corps publications and is implemented in coordination with the 1st Marine Division, 11th Marine Regiment, and subordinate batteries like Battery A, Battery B, and Battery C. Organizationally the battalion comprises firing batteries, a headquarters battery, and a combat logistics element that interfaces with Marine Corps Logistics Command and Combat Logistics Regiment 1 for sustainment. Command relationships involve the I Marine Expeditionary Force for large-scale operations, and the battalion routinely integrates with Marine Air-Ground Task Force components, the 1st Marine Aircraft Wing, and naval gunfire liaison teams that coordinate with United States Navy destroyers and cruisers for maritime fires.

Deployments and Operations

The battalion has conducted amphibious assault support in operations associated with the Pacific Theater (World War II), supported counterinsurgency and conventional operations during Operation Desert Storm and Operation Iraqi Freedom, and executed fire support in Operation Enduring Freedom in Afghanistan. It has participated in multinational operations and exercises such as Exercise Talisman Sabre, RIMPAC, and bilateral training with Japan Ground Self-Defense Force and Republic of Korea Armed Forces. The unit's expeditionary deployments have frequently embarked aboard Wasp-class amphibious assault ships and integrated with Expeditionary Strike Group taskings, conducting live-fire missions, counterbattery missions, and joint fires coordination with United States Air Force close air support assets and NATO partner artillery units.

Equipment and Weapons

Historically equipped with towed and self-propelled systems, the battalion has fielded artillery pieces including the M198 howitzer, the M777 howitzer, and associated fire-control systems linked to the Advanced Field Artillery Tactical Data System. Indirect fires are delivered using munitions compatible with precision-guided technologies and fire-support coordination tools interoperable with Joint Fires Observer procedures and the Forward Air Controller community. Support equipment includes heavy-tow tractors, ammunition supply vehicles, and communications suites that connect to systems such as the Common Aviation Command and Control System and joint fire network nodes used by United States Central Command and United States Indo-Pacific Command.

Unit Honors and Awards

The battalion's campaign streamers and unit awards reflect participation in major campaigns including Guadalcanal Campaign and Battle of Okinawa streamers, as well as unit commendations for service in Operation Iraqi Freedom and Operation Enduring Freedom. Awards and citations have been conferred by authorities including the Department of the Navy and joint combatant commanders, recognizing meritorious unit commendations and campaign participation credits alongside decorations tied to coalition operations with NATO and allied forces.

Notable Commanders and Personnel

Leaders and personnel associated with the battalion have included career officers and senior noncommissioned officers who later served in commands within the 1st Marine Division, I Marine Expeditionary Force, and at headquarters such as Headquarters Marine Corps. Alumni have progressed to billets in joint staffs at United States European Command, United States Central Command, and positions within the Pentagon surface-to-surface fires and doctrine communities, contributing to interoperability with partners including the Australian Defence Force and Japan Ground Self-Defense Force.

Training and Exercises

Training emphasizes live-fire certification, fire-support coordination, and integration with combined-arms maneuvers conducted at locations such as Camp Pendleton, Marine Corps Air Ground Combat Center Twentynine Palms, and multinational training areas used during RIMPAC and Talisman Sabre exercises. The battalion trains in collective interoperability with Marine Aircraft Group aviation assets, United States Navy amphibious ships, and joint fire-control elements, employing doctrine from Marine Corps Warfighting Publication series and joint publications used by United States Joint Forces Command and theater commands.
