World War II
The 25th Marine Regiment was activated on May 1, 1943. The 25th Marine Regiment fought in the Battle of Saipan, Battle of Tinian, Kwajalein Atoll, and the Battle of Iwo Jima. During the battle for Iwo Jima the battalion was tasked with the securing of Airfield One, then further tasked with pushing northward into the heart of the Japanese defenses. Colonel Justice M. Chambers received the Medal of Honor for his actions as the Commander of 3/25 during the battle of Iwo Jima. His citation reads, in part, that while “exposed to relentless fire, he coolly reorganized his battle-weary men, inspiring them to heroic efforts by his own valor and in leading an attack on the critical, impregnable high ground.” His medals are displayed in the trophy case located at H&S Brook Park, Ohio.
In 1945 the regiment was deactivated when World War II had ended. On July 1, 1962 the 25th Marine Regiment was reactivated as a Marine Corps Reserve Unit. This Regiment has continued to train in “every clime and place” for its role in the defense of United States.
3rd Battalion 25th Marines was again activated during Operation Desert Storm to support operations conducted in Southwest Asia. Although the Marines of 3/25 did not deploy to Southwest Asia, they played a key role by participating in other operation the Marine Corps was committed to support. Marines from 3/25 found themselves in Norway, Panama, and Honduras.
Global War on Terror
The battalion was activated on January 4, 2005. From Jan 10 to late February 2005, the companies conducted pre-deployment training at Marine Corps Air Ground Combat Center Twenty-nine Palms and March Air Reserve Base, California. The battalion was in Iraq by the first week of March 2005, tasked with training the Iraqi Security Forces (ISF) and conducting stability and security operations to prevent insurgents from gaining a foothold in and around the cities of Iraq’s Al Anbar province.
Major operations that the battalion participated in include Operation Matador, Operation New Market, Operation Spear, Operation Sword, Operation River Bridge, Operation Outer Banks, and Operation Quick Strike.
The battalion rotated out of Iraq in late September 2005, and deactivate on January 3, 2006. Forty-six Marines and two navy Corpsman serving with the battalion in Iraq were killed in action. A memorial paying tribute to them was erected at the Battalion headquarters in Brook Park, Ohio and was dedicated on November 12, 2005.
