The 196th Infantry, also known as the Charger Brigade, was first formed on 24 June 1921 as part of the United States Army Reserve's 98th Division with the responsibility of training soldiers.

During World War II, the 98th initially defended Kauai, Hawaii and Maui, Hawaii, and finally responsible for defending Oahu, Hawaii later in the war. The Division began intensive training in May 1945 to prepare for the invasion of Japan, but the war ended before it could depart Hawaii. However, the unit arrived in Japan for occupation duty as the 3rd Platoon, 98th Reconnaissance Troop Mechanized, of the 98th Infantry Division, where it eventually was deactivated on 16 February 1946, in Charlotte, NC

The brigade was reactivated in September 1965 at Ft Devens Massachusetts, where it was originally scheduled to be sent to the Dominican Republic. Instead, the Army rushed it to Vietnam, the Brigade departing on 15 July 1966 via transport ships and arriving on 14 August 1966 at Tây Ninh Combat Base.

In April 1972, the 196th moved to Da Nang to assist in port security duties. Units of the brigade were rotated through Phu Bai Combat Base to provide base security. The brigade finally left Vietnam on 29 June 1972 as the last combat brigade to leave Vietnam. The 196th served in Vietnam from 15 July 1966 through 29 June 1972. The brigade suffered 1,188 killed-in-action, and 5,591 wounded-in-action during its service in Vietnam.

On 26 May 1998, the 196th Infantry Brigade was reactivated during a ceremony at Fort Shafter, Hawaii. The newly reflagged brigade, previously designated as the Training Support Brigade Pacific, is organized as a Training Support Brigade, and is assigned to United States Army Pacific (USARPAC). The 196th Infantry Brigade provides National Defense Authorization Act Title XI pre-mobilization, post-mobilization and demobilization support to Army reserve component units in Alaska, American Samoa, Arizona, the Commonwealth of Mariana Islands (CNMI), Guam, the Hawaiian Islands, Japan and the Republic of Korea
