A specialized Mexican Army unit that carried out the operation resulting in the death of Cartel Jalisco New Generation (CJNG) leader Ruben Nemesio “El Mencho” Oseguera Cervantes had recently received training from U.S. Navy SEAL instructors, according to confirmation obtained from high-level members of the U.S. intelligence community, as reported by Breitbart.

Breitbart Texas confirmed that Navy SEAL instructors traveled to Mexico earlier this month to conduct a series of training sessions focused on targeting and apprehending high-level cartel figures.

The training followed a controversial vote in Mexico’s Senate earlier this month, authorizing U.S. special forces operators to enter the country to train Mexican military personnel.

According to sources familiar with the matter, instructors from the U.S. Navy SEALs and other elite U.S. units are scheduled to remain in Mexico from mid-February through April.

The first group arrived on February 15 aboard a U.S. military air transport, bringing their own equipment and weapons to conduct the training seminars.

Sources told Breitbart Texas that when the selected Mexican Army team was assigned to the U.S. Navy SEAL instructors, the American trainers immediately collected the unit’s phones and all communication devices.

The measure was intended to prevent leaks of operational details, which have complicated previous attempts to capture El Mencho and other cartel leaders in recent years.

While specifics regarding both the training curriculum and the operation itself remain classified, Breitbart Texas confirmed that Mexican military forces, working with U.S. and Mexican intelligence, located El Mencho in Tlapalpa, Jalisco.

The operation was designed to apprehend the CJNG leader.

During the mission, CJNG security personnel engaged Mexican military forces in what authorities described as a fierce firefight.

Mexico’s military killed four gunmen and wounded three others. The injured suspects were airlifted to a hospital for emergency treatment, but died before reaching medical care.

According to information provided to Breitbart Texas by Mexico’s military, one of the individuals who died during the air transport was Oseguera Cervantes, widely known as El Mencho.

The CJNG leader had long been considered one of Mexico’s most powerful and violent cartel figures.

In the immediate aftermath of his death, cartel gunmen launched retaliatory acts across multiple Mexican states.

As previously reported by Breitbart Texas, CJNG members carjacked vehicles, established road blockades, and set buildings on fire in various regions. The unrest spread rapidly, disrupting transportation and daily life in affected areas.

The violence reached a level that prompted the U.S. Department of State to issue a travel warning to American citizens in Mexico, advising them of potential dangers tied to the cartel’s response.

The advisory highlighted the risk posed by organized criminal activity following the operation.

The joint intelligence effort and the presence of U.S. Navy SEAL instructors in Mexico marked a notable moment in cross-border cooperation aimed at dismantling cartel leadership.

The Mexican Senate’s authorization for U.S. special forces to conduct training inside the country cleared the way for the February 15 deployment and the subsequent training sessions that preceded the operation in Tlapalpa.

Details surrounding the coordination between U.S. and Mexican intelligence agencies have not been made public. However, officials confirmed that intelligence-sharing played a key role in tracking El Mencho to his location in Jalisco.
