Fort Johnson, formerly Fort Polk, is a United States Army installation located in Vernon Parish, Louisiana, about 10 miles (15 km) east of Leesville and 30 miles (50 km) north of DeRidder in Beauregard Parish.

Named after New York soldier William Henry Johnson, the post encompasses about . Some are owned by the Department of the Army and by the U.S. Forest Service, mostly in the Kisatchie National Forest. In 2013, there were 10,877 troops stationed at Fort Johnson, which generated an annual payroll of $980 million. Louisiana officials lobbied the Army and the United States Congress to keep troop strength at full capacity despite looming defense cuts.

Fort Johnson

Fort Johnson began as a base for the Louisiana Maneuvers in the 1940s. It served the 1st Armored Division in the 1950s, and became a basic training post during Vietnam War years of the 1960s and '70s. It hosted the 5th Infantry Division (Mechanized) in the 1970s-1980s, and the 2nd Armored Cavalry Regiment in the 1990s and the 1st Maneuver Enhancement Brigade, and the 162nd Infantry Brigade in the 2000s. Fort Johnson is now home to the Joint Readiness Training Center (JRTC), the 3rd Brigade Combat Team, 10th Mountain Division, 115th Combat Support Hospital, U.S. Army Garrison and Bayne-Jones Army Community Hospital.

Fort Johnson

The land that is now Fort Johnson is part of a region of cultural resources, including archaeological sites, historic houses and structures, and other sites of historical value. The U.S. Army has spent considerable time, effort, and money to find and inventory thousands of archaeological sites on Fort Johnson and the property owned by the U.S. Forest Service where the Army trains.

Fort Johnson

Fort Polk became Fort Johnson during a re-designation ceremony on June 13, 2023 in honor of Sgt. William Henry Johnson, a World War I Medal of Honor recipient from North Carolina who served in the 369th U.S. Infantry Regiment.

History

1940s

World War II

Construction of Camp Polk began in 1941. Thousands of wooden barracks sprang up quickly to support an Army preparing to do battle on the North African, European and Pacific fronts. Soldiers at Polk participated in the Louisiana Maneuvers, which were designed to test U.S. troops preparing for World War II.

Until 1939, the Army had mostly been an infantry force with supporting artillery, engineer, and cavalry units. Few units had been motorized or mechanized. As U.S. involvement in World War II became more likely, the Army recognized the need to modernize the service. But it also needed large-scale maneuvers to test a fast-growing, inexperienced force. That is where Fort Polk and the Louisiana Maneuvers came in.

The Maneuvers involved half a million soldiers in 19 Army divisions, and took place over in August and September 1941. The troops were divided into equal armies of two notional countries: Kotmk (Kansas, Oklahoma, Texas, Missouri, Kentucky) and Almat (Arkansas, Louisiana, Mississippi, Alabama, Tennessee). These countries were fighting over navigation rights in the Mississippi River. The Maneuvers gave Army leadership the chance to test a new doctrine that stressed the need for both mass and mobility. Sixteen armored divisions sprang up during World War II after the lessons learned during the Louisiana Maneuvers were considered. These divisions specialized in moving huge combined-arms mechanized units long distances in combat.

On the defensive front, U.S. doctrine was based on two needs: the ability to defeat Blitzkrieg tactics; and how to deal with large numbers of German tanks attacking relatively narrow areas. As such, the Maneuvers also tested the concept of the tank destroyer. In this concept, highly mobile guns were held in reserve until friendly forces were attacked by enemy tanks. Then, the tank destroyers would be rapidly deployed to the flanks of the penetration. Tank destroyers employed aggressive, high-speed hit-and-run tactics. The conclusion drawn was that tank destroyer battalions should be raised. Immediately after the war, the battalions were disbanded and the anti-tank role was taken over by the Infantry, Engineer, and Armor branches.
