An Obscured Conflict: The role of the Mexican Armed Forces in the Fight Against Organised Crime (2001-2016

By Jan Slobodník

This study examines the militarised approach of the Mexican government in its struggle against organised crime between 2001 and 2016, focusing on the deployment of the armed forces and the implementation of the so-called kingpin strategy. It argues that the removal of cartel leaders, rather than weakening criminal networks, produced fragmentation, diversification, and militarisation within Mexico’s underworld—a process defined here as zetafication. The thesis uses the rise and evolution of Los Zetas as a case study to analyse how a criminal organisation born from army deserters introduced military tactics, hierarchical discipline, and extreme violence into organised crime, transforming the conflict’s character and the state’s response. Drawing on government reports, interviews with Mexican military officers and civilians, and contemporary scholarship, the study situates this phenomenon within Mexico’s political, legal, and socio-economic context, including the influence of U.S. security policy. It concludes that the use of the military as a policing tool produces short-term tactical gains but undermines long-term state stability, erodes public trust, and perpetuates cycles of violence.
