1st Marine Brigade

The 1st Marine Brigade, originally formed in 1912, has a distinguished history within the United States Marine Corps as an expeditionary unit. It saw early service in the Caribbean and Central America, participating in interventions such as those in Haiti and Nicaragua. During World War II, the brigade was reorganized and played a key role in the Pacific Theater, notably at the Battle of Guadalcanal. Over the decades, its designation and mission have evolved, but the unit’s legacy of rapid deployment and combat excellence remains central to its identity.
