Mexico’s Sinaloa Flooded With Troops as Police Lose Ground to Cartels

When police cannot control powerful drug cartels, Mexico sends in the army. This is playing out now in Sinaloa, a state long known as the center of drug trafficking.

In August 2025, the Mexican government deployed over 2,000 new soldiers to Culiacán, Sinaloa’s capital, pushing the total military presence in the state above 11,000. The government moved after police and local forces proved unable to handle the scale of cartel warfare.

This heavy militarization follows months of bloody clashes between rival groups within the Sinaloa cartel, which exploded after the arrest of longtime cartel boss Ismael “El Mayo” Zambada.

Official government sources confirm that in recent weeks, security forces have destroyed at least nine methamphetamine labs, confiscated 10,000kg of synthetic drugs, and seized a huge cache of weapons and ammunition—over 116 firearms and 24,000 rounds.

Yet, despite the soldiers everywhere, the violence keeps going. Mexican government crime records show Sinaloa still ranks among the most dangerous states, with murder rates among the country’s highest.

Troops have also arrested 65 suspected cartel operatives in the past two weeks, but this has not brought lasting calm. The reality is that the police are outmatched.

Sinaloa Cartels’ Power Drives Militarized Response

Drug cartels in Sinaloa run huge, well-armed networks and control much of the drug trade into the United States and other countries. Their operations are worth billions of dollars and rely on local corruption and fear.

Cartels defend clandestine drug factories with firepower far beyond what local police can handle. Mexico’s government treats this fight as an internal conflict, regularly replacing military commanders to ensure loyalty and reduce corruption.

Even the United States has intervened, seizing 50,000kg of chemicals headed for Sinaloa cartel labs in June. Officials on both sides of the border admit that these cartels run a global business, with violence in Sinaloa having direct economic and social impacts abroad.

This is the real story: Sinaloa stays militarized not because the police want it, but because without soldiers, criminal groups would run unchecked.
