Armed Forces of Paraguay
The Armed forces of Paraguay () consist of the Paraguayan army, navy (including naval aviation and marine corps) and air force. The constitution of Paraguay establishes the president of Paraguay as the commander-in-chief. Paraguay has compulsory military service, and all 18-year-old males and 17-year-olds in the year of their 18th birthday are liable for one year of active duty. Although the 1992 constitution allows for conscientious objection, no enabling legislation has yet been approved. In July 2005, military aid in the form of U.S. Special Forces began arriving at Paraguay's  Mariscal Estigarribia air base, a sprawling complex built in 1982. Army. In land forces the Paraguayan Army is composed of a Presidential Guards Regiment, composed two battalions (infantry and military police), an armored squadron, and a battery of field artillery, plus the operationally attached Mounted Ceremonial Squadron "Aca Caraya" (which serves independently but as the mounted escort in state events, and serves as part of the 4th Cavalry Regiment). Their equipment includes three Argentinean modified M-4 tanks, four EE-9 armored cars, four EE-11 armored personnel carriers (APCs), three M-9 half-tracks mounting 20mm guns, and four M-101 105 mm  howitzers. Arguably, this "flagship" of military rule is structurally and physically the strongest of the EP. The REP is an independent unit from other commands. The EP features two artillery groups (GAC 1–12 88 mm QF-25 and GAC 2–12 105mm M-101) and one antiaircraft artillery group (GAA 13 40 mm L 40/60, Oerlikon 20 mm cannons, and six M-55 4x12, 7.0 mm).

This has little organic aviation available to it. Each corps has a weapons school run by its command. The logistical command manages 10 addresses materials, mobilization, health care, etc. The command of the Army Institute of Education administers three schools, commissioned and noncommissioned officers, a military academy, and the CIMEFOR (a center for pre-military study that trains Reserve officers). Each of the nine divisions that make up the three corps has one or two regiments of infantry or cavalry, its platoon of engineers, its communications section, military police units , etc. Navy. Although Paraguay is a landlocked country, it has a strong naval tradition by virtue of the fact that it has access to the Atlantic Ocean through the Paraguay–Paraná rivers. The Paraguayan Navy has twelve bases. The main base is the Puerto Sajonia in Asuncion, followed by Bahia Negra, Ciudad del Este, Encarnacion, Salto del Guaira. It also has facilities in Puerto Sajonia for helicopters and airplanes in SGAS. Naval personnel including Marine Corps aviation personnel, and the naval inward waters prefecture equal about 8,950. The Marine Corps have 800 marines, of which 400 are assigned to one  commando unit with the rest being organized into a single battalion consisting of three companies. In terms of vessels, the Navy has 34 surface ships, some of which have reached centenarian age. (This is due in part to limited use and floating in fresh water.) The main vessels and the flagship of the Paraguay Navy is still "Humaita", which was commissioned prior to Paraguay's involvement in the Chaco War. It has a further four patrol vessels, of which the oldest was commissioned in 1908 and the newest in 1985. The Navy has 17 patrol boats of various drafts, four  of which were donated by Taiwan and the United States, while the other 13 were built locally. The rest of the fleet is composed of tugboats, barges, landing craft, transports, and a presidential yacht. The new additions are four Croc-class riverine vessels from Australia, plus 43 locally built riverline patrol vessels constructed from 2006–2009.
