Central Bloc of the FARC-EP
The Central Bloc of the Revolutionary Armed Forces of Colombia operated strategically in the Andes Mountains, around the middle of Colombia. The group was considered as the largest threat to Bogotá and its economy, as it operated in areas surrounding the capital. Strong military action in the 2000s, however, forced the bloc to hide in remote parts of the mountains, away from many highways and cities.
The specific divisions of the group are arguable.bSome 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. For more general information see FARC-EP Chain of Command.
