Assault craft are specialized military vessels designed for transporting troops and equipment during amphibious operations. They are built to operate in shallow waters, allowing them to approach shorelines where larger ships cannot. These craft can be used for various missions, including beach landings and quick insertions of forces. Typically, assault craft are equipped with features like ramps for easy loading and unloading, and some may have armament for self-defense. They play a crucial role in operations conducted by military branches such as the U.S. Navy and Marine Corps, facilitating rapid deployment in combat scenarios.
