U.S. and Portuguese Marines execute an amphibious landing in Pinheiro Da Cruz, Portugal

U.S. Navy hovercraft came from the USS Arlington around 100 kilometers (60 miles) south of the Portuguese capital Lisbon, generating clouds of spray and noise as they delivered U.S. and Portuguese Marines and armored vehicles to the beach while U.S. Navy helicopters flew overhead.

In the imagined scenario, NATO was projecting force to help a friendly country that requested help to re-establish order.
