Operation Attleboro was a Vietnam War search and destroy operation initiated by the 196th Light Infantry Brigade with the objective to discover the location(s) of People's Army of Vietnam (PAVN) and Viet Cong (VC) base areas and force them to fight. The operation was named after Attleboro, Massachusetts, where the brigade had been formed. Operation Attleboro grew to be the largest series of air mobile operations to that time, involving all or elements of the 196th Brigade, 25th Infantry Division, 1st Infantry Division and a brigade of the 4th Infantry Division, as well as numerous Army of the Republic of Vietnam and Regional Forces/Popular Forces and Nùngs. In the end, the operation became a Corps operation commanded by II Field Force, Vietnam.

The 25th Infantry Division is a United States Army division based at Schofield Barracks in Hawaii. The division, which was activated on 1 October 1941 in Hawaii, conducts military operations primarily in the Asia-Pacific region. Its present deployment is composed of light infantry and aviation units. Tropic Lightning soldiers regularly train with other U.S. military branches to practice and maintain joint operations capabilities. The climate and terrain of the Pacific region demands Tropic Lightning soldiers be able to operate in physically demanding and harsh environments. In 2014, the division opened the Jungle Operations Training Center—the first such school in the Army since the closing of the old Jungle Warfare School at Fort Sherman, Panama Canal Zone. Joint operations and training with partner states herald a new chapter in the history of Tropic Lightning—America's Pacific Division.
