Which military branch is specifically responsible for amphibious operations?

The Marine Corps is specifically responsible for amphibious operations due to its unique role and training within the U.S. military framework. Amphibious operations involve the coordinated assault and seizure of territory from the sea, and the Marine Corps is structured, trained, and equipped specifically for these types of missions.

Marines receive specialized training that prepares them to operate effectively in both land and sea environments. This includes proficiency in conducting operations from naval vessels, performing beach landings, and securing coastal regions. They are the first force on the scene in crisis response and are perfect for rapid deployment, which is critical in amphibious operations.

While the Navy plays a supportive role in amphibious operations through transport and naval gunfire support, and the Army has capabilities for a variety of operations, the Marine Corps' defined mission and readiness for amphibious assaults make it the branch specifically tasked with these operations.
