The 3rd Battalion, 1st Marines (3/1), known as the "Thundering Third," was activated in March 1941 and saw extensive combat during World War II, including battles at Guadalcanal, Peleliu, and Okinawa. During the Korean War, 3/1 participated in key engagements such as the Inchon Landing and the Battle of Chosin Reservoir. In the Vietnam War, the battalion was heavily engaged in operations throughout the northern provinces, notably during the Tet Offensive. More recently, 3/1 has served in Iraq and Afghanistan, playing significant roles in the Second Battle of Fallujah and counterinsurgency operations.
