4th Tank Battalion

The 4th Tank Battalion is a unit of the United States Marine Corps Reserve, originally activated in 1943 during World War II. It played a pivotal role in several major Pacific campaigns, including the Battle of Kwajalein, Saipan, Tinian, and notably Iwo Jima, where its tanks famously supported the assault on Mount Suribachi. After World War II, the battalion was deactivated but later reactivated in the Marine Corps Reserve, participating in training and readiness exercises. The 4th Tank Battalion also saw combat in the Gulf War, providing vital armored support during Operation Desert Storm before its final deactivation in 2021 as part of a Marine Corps force restructuring.
