Amphibious warfare is a military operation that involves the movement of forces from sea to land. This type of warfare combines naval and ground forces to conduct assaults on enemy positions, often using specialized ships and landing craft. The goal is to establish a foothold on land, allowing for further military operations. Successful amphibious operations require careful planning and coordination between different branches of the military. Key elements include reconnaissance, logistics, and the use of naval forces to support ground troops. Historical examples include the D-Day invasion during World War II, which showcased the effectiveness of amphibious tactics.
