1st Battalion, 24th Marines (1/24) is a reserve infantry battalion in the United States Marine Corps located throughout Michigan, Ohio, and Indiana consisting of approximately 1,000 Marines and Sailors. Nicknamed Terror from the North, the battalion is attached to the 25th Marine Regiment of the 4th Marine Division.

Provide trained combat and combat support personnel and units to augment and reinforce the active component in time of war, national emergency, and at other times as national security requires; and have the capability to reconstitute the Division, if required.

On July 5, 1922, the Marines first came to Detroit when a volunteer Marine Corps Reserve company was activated with a strength of 70 men. In 1926 the company designated as the 306th Company of the Fleet Marine Force (FMF) Reserve before being redesignated in 1929 as Company "B" of the 8th Reserve Battalion, headquartered in Toledo, Ohio.

In October 1938, Detroit became the home of a second company of Marines, Company "D" of the 8th Reserve Battalion. Shortly thereafter, in November 1940, the 8th Reserve Battalion was mobilized as an individual active duty battalion before being integrated into the First Marine Brigade in January 1941. As part of the First Marine Brigade, the battalion fought valiantly in World War II in the South Pacific.

In August 1946, the battalion was formed into the 17th Infantry Battalion. Four years later, the reservists of the 1st Battalion were mobilized and reported to Camp Pendleton, California, where many joined the units of the 1st Marine Division in Korea in the fall and winter of 1950.

In July 1962, the Marines became Headquarters & Service Company of the 1st Battalion, 24th Marine Regiment when the 4th Marine Division was reactivated. 1/24 was mobilized in support of Operation Desert Shield in December 1990. The unit was sent to Okinawa and the Philippines where they assisted in rescue operations associated with the eruption of Mount Pinatubo.
