National Defense is much more than the military: it's an organized system designed to guarantee Spain's sovereignty, security, and well-being against external threats. In this article, we explain what Defense actually encompasses, how it's structured, what functions it performs, and how you can begin your journey in this highly strategic and vocational field.

What is National Defense?

National Defense is the set of human, material, and strategic resources that a country employs to guarantee its territorial integrity, independence, and sovereignty . In Spain, it is regulated by Organic Law 5/2005 and reports to the Ministry of Defense.

It's not limited to the Armed Forces: it also involves the government, public administrations, strategic companies, and, in crisis situations, even citizens.
