Colombian security forces attacked a camp belonging to the Revolutionary Armed Forces of Colombia (FARC) on March 26 in Vistahermosa, Meta department, killing 36 members of the guerrilla group and capturing three. The operation, which Colombian President Juan Manuel Santos said resulted in the deaths of more FARC members than any other single strike in the 50-year-long conflict between the Colombian government and Marxist guerrilla groups, came shortly after a similar action in Arauca state in which 33 FARC members were killed and 12 were captured.

The operations were launched as part of an aggressive new Colombian counterinsurgency strategy dubbed Operation Espada de Honor ("Sword of Honor"), created in response to the increasing violent activity by the country's guerrilla groups. The plan expands the list of targets for security forces and the locations where they will engage guerrillas, with the goal of crippling the FARC both militarily and financially.

Espada de Honor is the latest of several plans by the Colombian government to combat militancy in the country. To fully understand the plan and its implications, it is helpful to examine the nature of Colombia's guerrilla groups, previous government counterinsurgency strategies and how the FARC has reacted to them.
