Landing Zone Columbus

Landing Zone Columbus. It was a Fire support base established by the 1st Infantry Division in February 1967 during the Vietnam War. The base was constructed as part of the large-scale Operation Junction City, which aimed to disrupt Viet Cong and People's Army of Vietnam forces in War Zone C. Situated in Tây Ninh Province near the Cambodia–Vietnam border, it served as a critical hub for Artillery support and Helicopter operations.

History

The establishment was ordered by Military Assistance Command, Vietnam as a forward position for the sweeping maneuvers of Operation Junction City. Engineers from the 1st Engineer Battalion rapidly cleared the landing zone, which was initially secured by elements of the 2nd Battalion, 28th Infantry Regiment. Its creation followed the model of other bases like Landing Zone Gold and was designed to interdict enemy supply lines along the Ho Chi Minh trail. The site was selected for its strategic position to support operations against suspected Central Office for South Vietnam locations.

Description

The firebase was constructed as a compact, fortified artillery position typical of United States Army installations in the region. Its defenses included berms, Barbed wire obstacles, and a perimeter of Claymore mines and Machine gun bunkers. The central feature was a circular arrangement of 105mm howitzer firing pits, with a Helicopter pad for resupply and Medical evacuation by UH-1 Iroquois helicopters. Support facilities included a Tactical Operations Center, ammunition storage points, and living areas for the garrison, all built to withstand mortar and Rocket-propelled grenade attacks.

Operations

Primary missions included providing indirect fire support for infantry battalions such as the 16th Infantry Regiment and the 26th Infantry Regiment operating in the surrounding jungle. Its artillery, often from C Battery, 2nd Battalion, 33rd Artillery Regiment, participated in numerous pre-planned strikes and Counter-battery fire missions. The base also launched and supported daily Combat patrols and Search and destroy operations into adjacent areas like the Long Nguyen Secret Zone. It faced periodic Viet Cong probes and sustained Rocket attacks, particularly during the Tet Offensive in early 1968.

Units stationed

The garrison typically comprised a rotating mix of infantry, artillery, and support units. Key units that operated from the location included the 2nd Battalion, 28th Infantry Regiment, the 1st Battalion, 5th Artillery Regiment, and detachments from the 7th Engineer Battalion. Support was provided by the 588th Engineer Battalion for construction and the 1st Squadron, 4th Cavalry Regiment for perimeter security. Air cavalry troops from the 1st Cavalry Division also used it as a forward refueling point during extended reconnaissance missions.

Legacy

Like many forward firebases, it was abandoned and dismantled as part of the broader Vietnamization policy and the Withdrawal of U.S. troops from Vietnam. Its operational history is documented in unit records of the 1st Infantry Division and studies by the United States Army Center of Military History. The tactics of rapid airmobile base construction and artillery support pioneered at such locations influenced later United States military doctrine. The site remains a subject of study for historians analyzing Operation Junction City and the Military tactics of the Vietnam War.
