In Paraguay, the Paraguayan military is responsible for external defense but also has some domestic security duties; while the National Police are responsible for maintaining internal security, the military works with the police through a Joint Task Force (Fuerza de Tarea Conjunta or FTC) in combatting the Paraguayan People’s Army (Ejército del Pueblo Paraguayo or EPP) and transnational criminal organizations; the military has an Internal Defense Operations Command (Comando de Defensa Interna or CODI), which includes the Army, Navy, and Air Force, to coordinate internal security support to the police and other security organizations, such as the National Anti-Drug Secretariat or SENAD

the EPP is a domestic criminal/guerrilla group initially dedicated to a Marxist-Leninist revolution in Paraguay that operates in the rural northern part of the country along the border with Brazil; the activities of the EPP and its offshoots—Marsical López’s Army (EML) and the Armed Peasant Association (ACA)—have consisted largely of isolated attacks on remote police and army posts, or against ranchers and peasants accused of aiding Paraguayan security forces

the Paraguayan military is a small force by regional standards, and its limited equipment inventory is largely obsolete, with some of it pre-dating World War II; it has deployed small numbers of troops on UN missions and cooperates with neighboring countries, such as Argentina and Brazil, on security issues, particularly organized crime and narco-trafficking in what is known as the Tri-Border Area; Paraguay has not fought a war against a neighboring country since the Chaco War with Bolivia in the 1930s (2024)
