Donald Roebling changed the Marine Corps with his invention of the Alligator in 1937. Since then, the crews who tirelessly operated, maintained, and supported the long lineage of amphibious tractors have helped ensure the Marine Corps' success in virtually every conflict since World War II. From the islands of the Pacific to the sands of Iraq and Afghanistan, the amphibious tractors have held true to their purpose in supporting combat operations. But the freedom Americans enjoy is not without a heavy cost. Please take a moment to remember your brothers who made the ultimate sacrifice.

YAT-YAS! is dedicated to the Amtrac operators and mechanics of the Marine Corps. It is a community for Amtrac Marines who want a place to share stories, exchange knowledge, learn something, and network with their brothers from the Marine Corps. All generations of Amtrac Marines are welcome!
