First Armored Amphib Btn.

• WWII Origins: The First Armored Amphibian Battalion (1st Armored Amphibian Battalion) was activated in 1943 as part of the U.S. Marine Corps’ expansion of amphibious capabilities during World War II. • Specialized Vehicles: The unit was equipped with Landing Vehicle, Tracked (LVTs), also known as “Amtracs,” which could move from ship to shore and provide fire support with mounted cannons. • Saipan Landings: The battalion played a vital role in the June 1944 invasion of Saipan, providing armored firepower in the initial assault waves. • Battle of Tinian: 1st Armored Amphibian Battalion famously supported the innovative “shallow water landing” on Tinian, using LVTs to traverse coral reefs and land Marines where defenses were weaker. • Heavy Fire Support: Their LVT(A)-4s were armed with 75mm howitzers, allowing them to directly engage Japanese bunkers and tanks from the shoreline. • Okinawa Campaign: The battalion was heavily engaged during the 1945 Okinawa assault, where their armored vehicles provided key support in the challenging terrain and under constant enemy fire. • Casualties and Heroism: The battalion suffered significant casualties during these operations but earned numerous awards for bravery, including Silver Stars and Navy Crosses for individual Marines. • Pioneering Amphibious Tactics: The training and tactics tested by the 1st Armored Amphibian Battalion during WWII became the foundation for modern Marine Corps amphibious doctrine. • Disbandment and Legacy: The unit was deactivated after World War II, but its innovations influenced postwar armored and amphibious vehicle development. • Commemorated in Museums: Restored LVTs used by the 1st Armored Amphibian Battalion can be seen in military museums such as the National Museum of the Marine Corps, preserving their legacy for future generations.
