The article elaborates on the elite unit of the Mexican army that was instrumental in the operation that led to the death of Nemesio Oseguera Cervantes, known as 'El Mencho', who was the head of the Jalisco New Generation Cartel (CJNG). Before this operation, details about this special forces group were not widely known, but their successful mission has drawn significant attention in a country grappling with escalating drug-related violence.

Following the demise of 'El Mencho' on February 22, during a special forces operation in a private residence in Tapalpa, Jalisco, the article sheds light on the rigorous training that these soldiers undergo. Notably, the Associated Press was granted access to observe a training session of this elite group, popularly known as the 'murciélagos', which took place at high altitudes in the Iztaccíhuatl Popocatépetl National Park, showcasing their physical and tactical preparatory work in harsh conditions.

The implications of this operation are significant for Mexico, as 'El Mencho' was a key figure in the ongoing drug war that has plagued the nation. The successful neutralization of such a prominent cartel leader could potentially reshape the dynamics of power among drug trafficking organizations and may lead to either a temporary decrease in violence or a shift in tactics and leadership within the CJNG and other rival cartels, which are vying for control of territories impacted by drug-related conflicts.
