What are the types of amphibious movements?

The correct answer highlights two key types of amphibious movements: over-the-horizon operations and direct assault operations.

Over-the-horizon operations involve launching amphibious assaults from a distance, typically utilizing naval and air assets to project power without requiring immediate proximity to the shoreline. This approach allows forces to maintain an element of surprise and reduces vulnerability during the amphibious phase. Direct assault operations, on the other hand, are characterized by landing troops directly onto hostile beaches or shores, often in a swift and forceful manner to establish a foothold.

These two types are fundamental to amphibious warfare and are employed in various military strategies to ensure a successful landing and subsequent operations on land. Understanding these distinctions is crucial for effectively planning and executing amphibious operations, as they require different tactics, logistics, and considerations for the success of the mission.
