An amphibious assault is a military operation that involves attacking an enemy from both land and sea. This type of operation typically requires specialized forces, such as the U.S. Marine Corps, to land on a beach or coastal area, often using ships and landing craft. The goal is to establish a foothold on land, allowing for further military operations. These assaults are carefully planned and executed, often involving air support and naval bombardment to weaken enemy defenses. Successful amphibious assaults can be crucial in gaining territory and achieving strategic objectives during conflicts, as seen in historical events like the D-Day invasion during World War II.
