The 23rd Infantry Division, initially, and more commonly known as, the Americal Division, of the United States Army was activated 27 May 1942 on the island of New Caledonia. In the immediate emergency following Pearl Harbor, the United States had hurriedly sent a task force to defend New Caledonia against a feared Japanese attack. This division was the only division formed outside of United States territory during World War II. At the suggestion of a subordinate, the division's commander, Major General Alexander Patch, requested that the new unit be known as the Americal Division—the name being a contraction of "American, New Caledonian Division". This was unusual, as all other U.S. divisions are known by a number. After World War II the Americal Division was officially re-designated as the 23rd Infantry Division. However, it was rarely referred to as such, even on official orders.

Its present deployment is composed of Stryker, light infantry, airborne, and aviation units. Tropic Lightning soldiers serve as the premier Army response force for the U.S. Pacific Command, and 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.
