2:23rd Marines

U.S. Marine Corps

The 2nd Battalion, 23rd Marines (2/23) is a distinguished infantry battalion of the United States Marine Corps Reserve, activated during World War II in July 1942. The unit saw fierce combat in the Pacific Theater, notably participating in the pivotal battles of Roi-Namur, Saipan, Tinian, and Iwo Jima. After the war, 2/23 was deactivated but later reactivated as a reserve unit, continuing its tradition of excellence and readiness. In recent decades, 2/23 has supported numerous training, humanitarian, and operational deployments, including the Global War on Terror, upholding its legacy of valor and service.
