Eastern Bloc of the FARC-EP

The Eastern Bloc of the Revolutionary Armed Forces of Colombia, from September 2010 known as Bloque Comandante Jorge Briceño, in honour of the slain guerrilla leader,^[1] was considered to be the strongest military faction of the guerrilla group. It was divided into groups of 50–400 combatants in each group, which patrolled and controlled different areas of Colombia's Eastern and Central-Eastern territory, as well as helped to carry out the killings, taxation, and arrests necessary to advance the organization's financial and political goals.

The specific divisions of the group are arguable. Some of the believed divisions or 'fronts', as they were commonly called, are shown below. Many of these fronts sometimes worked together towards a certain mission, while others were further divided into 'columns' and 'companies' with a smaller number of members.
