Western Bloc of the FARC-EP

The Western Bloc of the Revolutionary Armed Forces of Colombia was the smallest of the Revolutionary Armed Forces of Colombia's (FARC) blocs in size, although not in military capability. It was often held responsible for attacks that occurred in Cali and the surrounding area. The specific divisions of the group are arguable. Some of its divisions or fronts, as they were commonly known as, are shown below. Many of these fronts worked together at times towards a certain mission, while others were further divided into columns and companies with a smaller number of members.
