Yet more grim evidence emerged this week that Mexico's warring cartels are becoming a real military force and underground parallel state in the country's lawless northeast. Small Wars Journal on Feb. 13 noted a press release from the Mexican attorney general's office, the PGR, announcing that federal police and army troops had raided a winery near Nuevo Laredo, Tamaulipas state, where 13 vehicles were being fitted with armor plating. Small Wars Journal calls it a "narco-tank factory." A huge amount of ammunition was also confiscated in the raid, although it seems the people who were running the workshop all escaped. The PGR said they believe the makeshift factory was being run by the Gulf Cartel.
