Although the FMLN continued to suffer from long-standing
sectarian rivalries, the FMLN groups--with Cuban training and
other assistance--reorganized during 1983. The FMLN divided the
country into five war fronts: the Feliciano Amo Western Front
(covering Ahuachapan, La Libertad, Santa Ana, and Sonsonate
departments), Modesto Ramirez Central Front (including Cuscatlan,
San Salvador, and parts of Cabanas and La Paz departments),
Anastasio Aquino Paracentral Front (comprising parts of Cabanas
and La Paz departments, as well as San Vicente Department),
Francisco Sanchez Eastern Front (covering La Union, Morazan, San
Miguel, and Usulutan departments), and Apolinario Serrano
Northern Front (consisting of Chalatenango Department).
The individual FMLN groups each claimed traditional areas of
operation and influence within the five FMLN fronts and were
organized on Marxist-Leninist structures. The ERP, which had a
Marxist-Leninist political front, the Party of the Salvadoran
Revolution (Partido de la Revolucion Salvadorena--PRS), was a
particularly well-organized group. Directed by its nine-member
general command, the ERP's principal force was the Rafael Arce
Zablah Brigade (Brigada Rafael Arce Zablah--BRAZ), which operated
on the Francisco Sanchez Eastern Front. The BRAZ was subdivided
into two groups consisting of several battalions. The FPL
operated on the northern, central, and western fronts. Directed
by a general command, composed of more than twenty-five
commanders, the FPL's leadership structure also included a
revolutionary council, a central committee, and a political
commission. The FPL's complex military structure was also
collectively known as the Popular Army of Liberation (Ejercito
Popular de Liberacion--EPL). Virtually indistinguishable from the
FPL, the EPL was composed of elite "vanguard units," less skilled
"guerrilla columns," and the "urban front" commando groups in the
cities.
Based primarily in the area of Guazapa Volcano, the FARN
served as the military apparatus of the National Resistance
(Resistencia Nacional--RN) party, a Marxist-Leninist political
front whose secretary general and second in command constituted
the FARN's general military command. The PRTC operated with other
FMLN groups through its armed wing, the Revolutionary Armed
Forces of Popular Liberation (Fuerzas Armadas Revolucionarias de
Liberacion Popular--FARLP). In addition to its rural forces, the
PRTC had a San Salvador-based terrorist apparatus called the
Mardoqueo Cruz Urban Guerrilla Commando. The PCES military wing,
the FAL, also reportedly was based at Guazapa Volcano, but its
principal rural guerrilla force operated mainly in northern and
central El Salvador. Although Handal commanded the FAL, it also
had an operational commander.
In the late 1980s, the rebels were still operating in small
units, avoiding confrontations with the army except on their own
terms, and emphasizing hit-and-run attacks mainly against
economic targets. In 1986 FMLN attacks on the economy increased
by 29 percent. The eastern region of El Salvador, the FMLN's main
area of operations, suffered the brunt of the sabotage campaign.
The FMLN facilitated its operations in El Salvador by using as
sanctuaries demilitarized border zones (bolsones), such as
north of the Torola-Jocoaitique line in northern Morazan
Department.
One of the FMLN's prime objectives was to sabotage the
country's economic infrastructure by attacking systematically
such targets as bridges, the power grid, and communications
equipment. Guerrilla forces also disrupted the transportation
system by paralyzing road traffic every month or two. The
intimidation of private investors through threats, "war taxes,"
kidnapping, and armed attacks on their business premises was
another aspect of this strategy, as was the infiltration of labor
unions in an effort to promote unrest. Guerrilla sabotage and
indirect economic losses caused by the war amounted to nearly
US$2 billion during 1979-88, more than the total amount of United
States economic assistance provided the country during the same
period. Salvadoran officials reported that 2,477 attacks on the
country's energy grid in the 1980-87 period destroyed 654 primary
and secondary distribution lines, costing US$51 million to
repair.
