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.

Its superior body, the Multi-National Force-Iraq (MNF-I) had replaced Combined Joint Task Force 7 on May 15, 2004. The change was made due to "concerns that had existed for some period of time, that the Combined Joint Task Force 7 headquarters was not sufficient to handle the range of military operations in Iraq, including peace support, civil military operations, and at the same time conduct strategic engagement such as talking to the sheiks and talking to the political authorities."
The United States Army Regimental System (USARS) is an organizational and classification system used by the United States Army. It was established in 1981 to replace the Combat Arms Regimental System (CARS) to provide each soldier with continuous identification with a single regiment, and to increase a soldier's probability of serving recurring assignments with their regiment. The USARS was intended to enhance combat effectiveness by providing the opportunity for a regimental affiliation, thus obtaining some of the benefits of the traditional regimental system.
