1:27th Marines

The 1st Battalion, 27th Marines (1/27), was activated in January 1944 as part of the 5th Marine Division during World War II. The battalion played a pivotal role in the Battle of Iwo Jima, participating in the intense fighting to secure the island. After the war, the unit was deactivated, but it was later reactivated during the Vietnam War, where it deployed in 1968 and conducted operations in the Quang Nam Province. The 1/27th Marines continue to serve as a reserve infantry battalion, maintaining readiness for deployment in support of Marine Corps missions worldwide.
