25th Infantry Division (United States)
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 infantry brigade combat team 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.
The division was originally activated from Hawaii garrison units during World War II, slightly more than two months before the Japanese attack on Pearl Harbor began the Pacific War. After spending almost a year training, it fought in the Allied counteroffensive during the Guadalcanal campaign from December 1942, helping to end organized Japanese resistance on that island by early February 1943. The 25th spent a period garrisoning the island, then moved on to fight in the New Georgia Campaign in July. After the Japanese defeat in the latter, it was sent to New Zealand later that year for rest and training, before moving to New Caledonia for further training. The division returned to combat in the January 1945 invasion of Luzon, reducing Japanese resistance on the island until late June, after which it was pulled out of the line for training. The division then served in the occupation of Japan after the surrender of the latter from September 1945.
When the Korean War began in June 1950, the division was deployed to South Korea, where it fought in the defense of and the breakout from the Pusan Perimeter in mid-1950, with elements advancing as far as the Amnok River in November. After being thrown back by the Chinese Communist intervention in the war, the division eventually took up positions south of Osan. It participated in a series of United Nations counteroffensives in early 1951, then fought in a stalemate close to the 38th parallel from the middle of the year. The division defended Seoul against Chinese Communist attack from May 1953 to the July armistice, returning to Hawaii in late 1954.
After undergoing major reorganizations in 1957 and 1963 to adapt to changing tactics, the division deployed to South Vietnam to fight in the Vietnam War between late 1965 and early 1966. The 25th served in Vietnam until its withdrawal back to Hawaii in 1970–1971, participating in Operation Attleboro, Operation Cedar Falls, Operation Junction City, the Battle of Saigon during the North Vietnamese Tet Offensive, and the Cambodian Incursion. It was reorganized as a light infantry division in 1985, and elements have participated in the Iraq War and the War in Afghanistan.

World War II
After the Japanese air attack on Schofield Barracks on 7 December 1941, the 25th Infantry Division moved to beach positions for the defense of Honolulu and Ewa Point.Following intensive training, the 25th began moving to Guadalcanal, 25 November 1942, to relieve Marines near Henderson Field. First elements landed near the Tenaru River, 17 December 1942, and entered combat, 10 January 1943, participating in the seizure of Kokumbona and the reduction of the Mount Austen Pocket in some of the bitterest fighting of the Pacific campaign. The threat of large enemy attacks caused a temporary withdrawal, but division elements under XIV Corps control relieved the 147th Infantry and took over the advance on Cape Esperance. The junction of these elements with Americal Division forces near the cape, 5 February 1943, ended organized enemy resistance.
A period of garrison duty followed, ending 21 July: On that date, advance elements debarked on Munda, New Georgia. The 25th Infantry, under the Northern Landing Force, took part in the capture of Vella Lavella, 15 August to 15 September 1943. Meanwhile, other elements landed on New Georgia, took Zieta, marched through jungle mud for 19 days, and captured Bairoko Harbor, winning the island. Elements cleared Arundel Island, 24 September 1943, and Kolombangara island with its important Vila Airport, 6 October. Organized resistance on New Georgia ended, 25 August, and the division moved to New Zealand for rest and training, last elements arriving on 5 December. The 25th was transferred to New Caledonia, 3 February-14 March 1944, for continued training.
The division landed in the San Fabian area of Luzon on 11 January 1945 to enter the struggle for the liberation of the Philippines. It drove across the Luzon Central Plain, meeting the enemy at Binalonan, 17 January. Moving through the rice paddies, the 25th occupied Umingan, Lupao, and San Jose and destroyed a great part of the Japanese armor on Luzon. On 21 February, the division began operations in the Caraballo Mountains in tandem with the 32nd Infantry Division which fought the Battle of Villa Verde Trail. The 25th fought its way along Highway No. 5, taking Digdig, Putlan, and Kapintalan against fierce Japanese counterattacks and captured Balete Pass, 13 May, and opened the gateway to the Cagayan Valley, 27 May, with the capture of Santa Fe. Until 30 June, when the division was relieved, it carried out mopping-up activities. On 1 July, the division moved to Tarlac for training, leaving for Japan, 20 September.

Korean War
The Korean War began on 25 June 1950 when the North Korean Korean People's Army crossed the 38th Parallel to invade South Korea. Acting under United Nations orders, the division moved from its base in Japan to Korea between 5–18 July 1950 to join the Eighth United States Army. The division, then under the command of Major General William B. Kean, successfully completed its first mission by blocking the approaches to the port city Pusan. For this action, the division received its first Republic of Korea Presidential Unit Citation. The division participated in the breakout from the Pusan perimeter commencing on 16 September and Eighth Army then began a general offensive northward against crumbling KPA opposition to establish contact with forces of the 7th Infantry Division driving southward from the Inchon beachhead. Major elements of the KPA were destroyed and cut off in this aggressive penetration; the link-up was affected south of Suwon on 26 September. On 23 September the division was assigned to the newly activated US IX Corps. The UN offensive was continued northwards, past Seoul, and across the 38th Parallel into North Korea on 1 October. The momentum of the attack was maintained, and the race to the North Korean capital, Pyongyang, ended on 19 October when elements of the Republic of Korea Army 1st Infantry Division and US 1st Cavalry Division captured the city. The advance continued, but against unexpectedly stiffening resistance. The Chinese People's Volunteer Army entered the war on the side of North Korea, making their first attacks in late October. The UN forces renewed their offensive on 24 November before being stopped by the PVA Second Phase Offensive starting on 25 November. The division was forced to carry out a systematic withdrawal and ordered to take up defensive positions on the south bank of the Chongchon River on 30 November 1950. Eventually, these lines failed and Eighth Army suffering heavy casualties, ordered a complete withdrawal to the Imjin River, near the 38th Parallel.After a month and a half of planning and reorganization, a new offensive was launched on 25 January 1951 and succeeded in recapturing Inchon and Kimpo Air Base. This was the first of several successful assaults on the PVA/KPA. The division next participated in Operation Ripper, during which it drove the PVA across the Han River. Success continued with Operations Dauntless and Piledriver in early 1951. These offensives secured part of the Iron Triangle which enhanced the UN's bargaining position. With leaders of four nations now at the negotiating tables in the summer of 1951, Division activity slowed to patrol and defensive actions to maintain the line of resistance. This type of action continued into the winter of 1952. In January 1953 the division was transferred from IX Corps to I Corps and assumed the responsibility of guarding the approaches of Seoul on 5 May 1953. 23 days later, when ceasefire negotiations at Panmunjom stalled, a heavy PVA assault hit the Nevada Complex, the division held its ground; the brunt of the attack was absorbed by the attached Turkish Brigade and the 14th Infantry Regiment. By successfully defending Seoul from continued attack from May to July 1953, the division earned its second Republic of Korea Presidential Unit Citation. Again, negotiators moved toward peace. In July, the division again moved to reserve status at Camp Casey where it remained through the signing of the armistice 27 July 1953. Fourteen division soldiers were awarded Medals of Honor during the Korean War, making the division one of the most decorated US Army divisions of that war.
The division's 14th Infantry Regiment had three recipients of the Medal of Honor, Donn F. Porter, Ernest E. West and Bryant E. Womack. The 24th Infantry Regiment had two recipients, Cornelius H. Charlton and William Thompson. The 35th Infantry Regiment had three recipients, William R. Jecelin, Billie G. Kanell and Donald R. Moyer. Finally, the 27th Infantry Regiment had five recipients, John W. Collier, Reginald B. Desiderio, Benito Martinez, Lewis L. Millett and Jerome A. Sudut. The divisions patch is sometimes referred to as the "Electric Strawberry".
The division remained in Korea until 1954 and returned to Hawaii from September through October of that year. After a 12-year absence, the 25th Infantry Division had finally returned home.
On 1 February 1957, the division was reorganized as a Pentomic Division. The division's three infantry regiments were inactivated, with their elements reorganized into five infantry battle groups.
In August 1963, the division was reorganized as a Reorganization Objective Army Division. Three Brigade Headquarters were activated and Infantry units were reorganized into battalions.
