About this Unit
The 3rd Marine Brigade was an expeditionary unit of the United States Marine Corps, activated at various times throughout the 20th century. During World War II, the brigade was briefly based at Kaneohe Bay, Hawaii, serving as a rapid reaction force for the defense of the Hawaiian Islands and as a staging element for operations in the Pacific Theater. Its presence at Kaneohe Bay contributed to the overall readiness and security of U.S. forces in the central Pacific following the attack on Pearl Harbor. The brigade was later reorganized and its personnel reassigned as the Marine Corps focused on offensive operations across the Pacific.
