The 58th Infantry was constituted on 15 May 1917 in the Regular Army as the 58th Infantry and organized 5 June 1917 at
Gettysburg National Park, Pennsylvania, from personnel of the
4th Infantry Regiment. Assigned to the
4th Infantry Division 19 November 1917. Inactivated 21 June 1922 at
Fort George Wright, Washington, disbanded 31 July 1922. • Company E served as a Long-Range Patrol (LRP) company to the 4th Infantry Division from 20 December 1967 – 1 February 1969, when all LRP companies were reflagged as lettered Ranger companies to the 75th Infantry Regiment. Co E 58th (LRP) would become Co K, 75th Infantry (RANGER) in 1969. • Company F served as a LRP company to the 101st Airborne Division (Airmobile) from 10 January 1968 – 1 February 1969 when it was reflagged as Co L, 75th Infantry (RANGER). By 1974 the 1st Battalion, 58th infantry was a mechanized infantry battalion assigned to the 197th Infantry Brigade (Separate) at Fort Benning, Georgia. The brigade was reorganizing as a separate mechanized infantry brigade with a go to war mission as the XVIII Airborne Corps heavy force package. During the period 1973-77 the battalion supported several important Army modernization initiatives. On return from three months of gunnery and maneuver training in 1976 at McGregor Range in New Mexico (the brigade and battalion had previously deployed from Kelley Hill Barracks at Ft. Benning to Eglin Air Force Base, Florida for a several week joint exercise), deployed Companies A and B for four months in support of the MICV (Mechanized Infantry Combat Vehicle) Developmental/Operational Tests 1 and 2. The MICV later became the Bradley Infantry Fighting Vehicle and the Tests also deployed the MILEs systems with their sensors, laser weapons effect systems and other force on force technologies later deployed to Fort Irwin and the National Training Center. Company A was assigned a tank platoon and additional tank section from 2d Battalion, 69th Armor. The company then trained and validated as a unit capable of replicating a Soviet motorized rifle battalion. Company B formed MICV configured platoons along with its M113A1 equipped platoons to operate as a U.S. ground force against a Soviet ground force. The two companies were deployed almost continuously for four months in the Turrentine Range Area and other locations on Fort Benning performing one force on force exercise after another to develop data that eventually led to the deployment of the Bradley Fighting vehicle to the Army. At the time Company A was an over-strength company of some 220 men (the then-MTOE authorized 187 men) having also been selected as a unit that would retrain NCOs in over strength MOSs as infantry NCOs. A provisional 4th mechanized infantry platoon was formed. This additional platoon with the three tank sections allowed the company to render a Soviet motorized rifle battalion footprint during the force-on-force exercises of the tests. All of this work made important contributions to the Army's highly effective heavy force capabilities that deployed in the two following Iraq Wars. The 2d Battalion, 58th Infantry was activated at Fort Hood, Texas on 1 April 1975, and assigned to the 2d Armored Division as part of Brigade 75, a program that stationed a forward brigade in Europe while maintaining three brigades at Fort Hood. The battalion deployed to Hohenfels Training Area in Germany in October 1976 as part of the rotations in place at the time, and redeployed in March 1977, remaining at Fort Hood until inactivation on 31 May 1981. On 28 August 1987, the unit was activated at Fort Benning as part of the United States Army Training and Doctrine Command. The coat of arms was originally approved for the 58th Infantry Regiment on 18 Jun 1921. It was amended on 20 Mar 1924 to correct the shield. On 15 Aug 1942 it was re-designated for the 58th Infantry Regiment (Reinforced). The coat of arms was re-designated for the 58th Infantry on 26 November 1958. ==Campaign streamers==
