Military - note

the Spanish Armed Forces have a wide variety of responsibilities, including protecting the country’s national interests, sovereignty, and territory, providing support during natural disasters, and fulfilling Spain’s responsibilities to European and international security; the military conducts operations worldwide, and its air, ground, and naval forces participate in a variety of EU-, NATO-, and UN-led missions; Spain joined NATO in 1982 and is fully integrated into the NATO structure; it routinely conducts exercises with EU and NATO partners, and hosts one of NATO’s two combined air operations centers 

the military is organized into commands for air, cyberspace, joint, land, maritime, and space operations; it also has a separate Emergency Response Unit, a permanent joint service force designed to respond to catastrophes and emergencies in both domestic and overseas environments; the Army is the largest service and has two divisional headquarters with several subordinate brigades of mechanized infantry and one of paratroopers; there are also separate commands for air defense, artillery, aviation, mountain troops, and special operations forces, as well as for the garrison units in the Balearic Islands, the Canary Islands, Ceuta, and Melilla

the basic structure of the Navy’s operational units includes surface and action forces, aviation and submarine flotillas, and a marine corps; the Surface Combat Force includes amphibious, mine warfare, surface warship, and escort squadrons and groups, while the Maritime Action Force is generally made up of units and assets whose main task is to conduct maritime security and surveillance operations in geographically based areas such as the Balearic and Canary islands, Cadiz, and Cartagena; the Navy’s principal warships include 11 frigates, four attack submarines, and three large helicopter-capable amphibious assault ships; it also has squadrons of multirole fighters and anti-submarine warfare aircraft; the 5,500-strong Marine Corps (aka Marine Infantry or Infantería de Armada) has amphibious, garrison, and special operations forces
