Third Generation Gangs and Transnational Cartels brings closure to the long running Small Wars JournalEl Centro Anthology series edited by Dr. John P. Sullivan and Dr. Robert J. Bunker under the auspices of the Small Wars Foundation. The curated work focuses on Latin American gangs, cartels, and the cross-cutting issues related to them. Its forty-four chapters and supporting front and back essays highlight the important contributions of some forty scholars and practitioners in the fields of criminal insurgency, gang studies, and transnational organized crime. The chapters span the mid-2018 through later-2024 period, with the inclusion of late 2024 and early 2025 essays specifically written to give context and provide analysis related to this work. The anthology benefits from a Foreword provided by Dr. Rashmi Singh, an Afterword offered by Dr. Alexandra Phelan, and a Postscript written by Dr. Mahmut Cengiz.
