The Armed Forces of El Salvador (Spanish: Fuerzas Armadas de El Salvador – FAES), which were backed by the United States, Taiwan and Israel, were the official armed defense forces of El Salvador. Subordinated to the Ministry of Defense and Security of the Salvadoran government at the capital San Salvador, the FAES branches were organized as follows:
The Farabundo Marti National Liberation Front (Spanish: Frente Farabundo Martí para la Liberación Nacional), more commonly known by its Spanish acronym FMLN, was an alliance or umbrella organization of five left-wing guerrilla groups created in 1980, which was backed by Cuba, Nicaragua, and the Eastern Bloc countries.
An eclectic variety of weapons was used by both sides in the Salvadoran Civil War. The Salvadoran FAES were equipped with Western-made weapons, mainly American and Israeli in origin, but also included Argentine, Portuguese, French, West German, Yugoslavian and Taiwanese military hardware. During the early phase of the war, the FMLN likewise were largely equipped with Western arms and munitions, though as the war went on, Eastern Bloc weaponry began to play a major role.
Heckler & Koch G3: Originally the standard service rifle of the Salvadoran Army before being replaced by the M-16A1/A2. The first G3s were of West German origin; however, when the U.S. began increasing small arms deliveries to El Salvador, they purchased surplus rifles from Portugal and gave them as military aid.[2][3][4]
M16A1/A2: The M16A1/A2 was initially issued to elite units before being issued to the rest of the army when it became the standard rifle. The first large-scale delivery occurred in 1981 with 11,868 units delivered. A total of 32,374 M16A1/A2 rifles were delivered between 1980 and 1993. The U.S. began to replace the G3 rifles in the hands of the Salvadorian Army in 1981 with the delivery of 11,868 AR-15A1 R613 (M16A1); followed by another 20,743 M16s purchased with FMS funds for El Salvador in 1982. Many of these "new" rifles were actually leftovers from Vietnam. Eventually, another 45,160 AR-15A1 R613 followed, to include more than 500 CAR-15A1 R639 (XM177E2 Commando – typified as M16A2 for El Salvador) to equip the Mechanized Infantry and officer Corps and hundreds of CAR-15A1 R653 (M16A1) Carbines starting in 1985, and even brand-new M16s supplied by Springfield Armory.[5][6]
CAR-15: Colt Automatic Rifle-15 Military Weapons System or CAR-15. The CAR-15: Colt Automatic Rifle-15 Military Weapons System or CAR-15 was delivered to all military branches of the Armed Forces of El Salvador and was also used with attached M203 grenade launchers.
Colt Commando (model 733, note M16A2-style brass deflector and forward assist), the USA military aid to El Salvador included the supply of this Car-15 variant that was used extensively by the Armed Forces of El Salvador. They also were used with attached M203 grenade launchers. The BIRI (immediate reaction infantry battalion) used this variant with the M203 attached.
T65 assault rifle: Taiwan had extensive diplomatic and military ties with El Salvador. Before and during the civil war, the Republic of China (Taiwan) sold weaponry including the T65 to the former Salvadoran security forces. Taiwan also trained Salvadoran military officers in the civil war; even after the end of the war, Taiwan had continued to give military advice and training to its diplomatic allies including El Salvador until 2018.
FN FAL: Most of the FAL rifles used by the guerrillas were traced by their serial numbers to rifles previously sold by Belgium to Cuba during the late Batista and early Castro years.[88][102][103]
M16A1: The bulk of the M16A1 rifles captured by government forces from the guerrillas were also traced from their serial numbers to shipments sent by the United States to the South Vietnamese Army of the Republic of Vietnam (ARVN) prior to the fall of the Saigon government in 1975.[105][106][107]
