Chile's Armed Forces are subject to civilian control exercised by the President through the Minister of Defense. Under the 1980 Constitution, the services enjoy considerable autonomy, and the President cannot remove service commanders on his own authority.

Army
The commander in chief of the Chilean Army is Maj. Gen. Juan Emilio Cheyre. The Chilean Army is 45,000 strong and is organized with an Army headquarters in Santiago, seven divisions throughout its territory, an Air Brigade in Rancagua, and a Special Forces Command in Colina. The Chilean Army is one of the most professional and technologically advanced armies in Latin America.

Navy
Adm. Miguel Vergara directs the 25,000-person Navy, including 5,000 Marines. Of the fleet of 29 surface vessels, only six are operational major combatants (destroyers and frigates). Those ships are based in Valparaiso. The Navy operates its own aircraft for transport and patrol; there are no fighter or bomber aircraft. The Navy also operates three submarines based in Talcahuano.

Air Force (FACH)
Gen. Osvaldo Sarabia heads a force of 12,500. Air assets are distributed among five air brigades headquartered in Iquique, Antofagasta, Santiago, Puerto Montt, and Punta Arenas. The Air Force also operates an airbase on King George Island, Antarctica.

Carabineros
After the military coup in September 1973, the Chilean national police (Carabineros) were incorporated into the Defense Ministry. With the return of democratic government, the police were placed under the operational control of the Interior Ministry but remained under the nominal control of the Defense Ministry. Gen. Alberto Cienfuegos is the head of the national police force of 30,000 men and women who are responsible for law enforcement, traffic management, narcotics suppression, border control, and counter-terrorism throughout Chile.
