These groups, known as "peasant leagues", established an interconnected network that coordinated protests and labor strikes, countered state-sanctioned violence, and sought to protect local populations.

PCC leadership, joined by guerilla leaders, established las "Fuerzas Armadas Revolucionarias de Colombia—Ejército del Pueblo" or Revolutionary Armed Forces of Colombia (FARC).

Three members of the PCC were known to have undergone training with the East German Ministry of State Security (MfS); such courses, provided by the "Task Force of the Minister, Responsibility Special Issues" ("Arbeitsgruppe des Ministers, Aufgabenbereich Sonderfragen"- AGM/S) and additionally accompanied by KGB officers, encompassed a wide range of paramilitary infiltration and sabotage techniques, but no additional details are known.

The PCC justified the operations of the guerrillas as the armed component of the fight against capitalism and imperialism in Colombia, while at the same time it continued to participate in legal electoral activities independently.

Other disagreements would include that the PCC may have allegedly tended to follow the changes that developed within the official Soviet line during the Cold War, which the FARC-EP did not consider as strictly binding.

Supporters of David Ravelo, a member of the PCC's central committee who is serving an 18-year sentence for plotting to murder a municipal official, contend that he is a political prisoner who was prosecuted illegitimately.
