end of the World War I, the Battle of Gallipoli made almost all countries abandon the idea of amphibious assault. The world's marine corps fell into a deep crisis, with the Spanish Marine Infantry being no exception, though it enjoyed success during the Third Rif War in its innovative Alhucemas amphibious assault in 1925, when it employed coordinated air and naval gunfire to support the assault. Owing to its high-profile action in the unpopular Rif Wars, the Spanish Navy Marine corps was branded as a leftover of the Spanish colonial era. After the proclamation of the Second Spanish Republic in 1931, the reforms of the armed forces introduced by newly nominated Republican Minister of War Manuel Azaña within the first months of the new government sought to disband the corps. Before it was officially disbanded, however, the Spanish Civil War intervened and the corps split and served both sides with the garrisons of Ferrol and Cádiz on the Nationalist side and the garrison of Cartagena, as well as a detachment in Madrid, on the Republican side. During the bitterly fought war the Marines performed garrison duties, led landing parties, and provided expert artillery and machine gun crews.

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. The Tercio de Armada (TEAR) became the main amphibious unit and has experienced several restructures that led to the E-01 Plan, which defines the requirements and structures from the year 2000 for the Spanish Marine Infantry. The Spanish Marines have been present in Europe, Central America and Asia in an anonymous role as an "emergency force" ready to evacuate civilians in conflict areas, or as
