South of the border, and probably well across it, the Mexican cartels have learned the lessons of postmodern warfare.

A group of cartel gunmen used land mines and weaponized drones in a series of ambush-style attacks where they killed at least four Mexican Army soldiers and injured several others. The gunmen managed to escape.

The attacks took place on Thursday afternoon in the rural areas of Michoacán near the town of Tepalcatepec, a region known for its heavy cartel presence by gunmen from both Cartel Jalisco New Generation and their rivals with Carteles Unidos, a group of smaller organizations including self-defense groups, Los Viagras, La Familia and others that banded together.

A convoy of Mexican soldiers was traveling along a dirt road when cartel gunmen set off a series of land mines. The cartels also began using drones to drop explosives on the soldiers. Gunmen hiding in the brush started firing at the soldiers.

Allegedly, they have much heavier weapons they’ve so far held back. More of this is coming and it won’t stay confined to cartel activity in Mexico. This is the kind of thing I keep talking about with the “second level” of warfare coming to ‘Murika once everything gets going. As unpleasant as it is and will be, it’s nothing compared to what level three will bring. Then we will find out what lessons ‘Murikans have learned if that’s even a possibility. Buckle up.
