Guerra de Ifni
After the civil war, during the dictatorship of Francisco Franco, the strength of the Infantería Marina was increased. In 1957, the "Grupo Especial Anfibio" (Amphibious Special Group) was created, and the Spanish Marine Infantry returned to its primary duty as a Landing Force Mission. In 1958 it established a beachhead in Spanish Sahara and Ifni during the Ifni War. The capabilities and strength of the Spanish Marine Infantry were increased: new amphibious vehicles, anti-tank weapons, individual equipment and artillery.
