3rd Engr Bn, 3rd Mar.Div

• Origins in World War II: The 3rd Engineer Battalion, 3rd Marine Division, was originally activated on September 16, 1942, at New River, North Carolina, as the 1st Battalion, 19th Marines, supporting amphibious operations in the Pacific. • Island Hopping Campaign: The battalion participated in major Pacific battles during WWII, including Bougainville, Guam, and Iwo Jima, performing critical tasks such as demolitions, construction, and clearing obstacles under fire. • Iwo Jima Heroics: During the Battle of Iwo Jima, 3rd Engineers played a vital role in clearing minefields, opening roads for tanks, and constructing fortifications under constant threat from Japanese defenders. • Korean War Reactivation: The battalion was deactivated after WWII, but reactivated for the Korean War, reflecting the Marine Corps' tradition of rapidly mobilizing engineer units for combat needs. • Vietnam War Service: The 3rd Engineer Battalion deployed to Vietnam in 1965 and was heavily involved in constructing bases, roads, airfields, and fortifications, as well as supporting combat operations across I Corps. • Diversified Missions: Besides combat engineering, the 3rd Engineers undertook humanitarian missions, including rebuilding communities and infrastructure in war-torn areas of Vietnam. • Post-Vietnam Deployments: The battalion continued to serve in peacetime exercises and deployments across the Pacific, including Okinawa, maintaining readiness for contingency operations. • Modernization and Technology: Over the decades, the 3rd Engineers have adapted to new technologies, including the use of mine-resistant vehicles, advanced construction equipment, and updated breaching techniques. • Disaster Relief Operations: The battalion has participated in humanitarian assistance and disaster relief missions, such as helping after typhoons and earthquakes in the Asia-Pacific region. • Motto and Legacy: The 3rd Engineer Battalion's motto, “Avante!” (meaning “Forward!”), reflects its longstanding tradition of leading from the front and overcoming obstacles in both combat and peacetime operations.
