Tubeless Artillery and Planeless Bombs

With its sophisticated tactical and strategic doctrine and prodigious armaments acquired largely from sympathetic Marxist governments – largely via Cuba and Nicaragua – the FMLN was quickly becoming the largest and strongest insurgency in Latin American history. A few years into the war, the guerrillas were now benefiting from finally being able to overcome their factional rivalries to launch coordinated strikes and share intelligence and resources. This allowed the rebels to launch operations that at times involved thousands of soldiers, a stunning level of strength and sophistication for a guerrilla movement in Latin America.

In 1982, the FAES captured a large cache of documents from an FMLN safe house in San Salvador. The secret documents revealed that Cayetano Carpio's FPL faction had identified the use of elite commando units as a key element of the insurgent strategy. The guerrillas believed that these crack troops would serve as the “tubeless artillery” and “planeless bombs” needed to carry out the stunning raids that would humiliate the Salvadoran military and remind the country of the guerrillas’ invincibility. FMLN soldiers had in fact started receiving training in Cuba as early as 1980. By 1983 these units were ready to go into action to strike at the heart of the FAES.
