The Mexican Army seized a pair of homemade narco tanks near the Texas border following a deadly gunfight in the state of Tamaulipas.

A drug cartel created armored vehicles by converting trucks that can withstand fire from .50-caliber machine guns and grenades. The vehicles are covered with one-inch thick steel plating, air-conditioned and are sized to hold 20 armed combatants.

The tanks were discovered in Ciudad Camargo after a shootout between a Mexican army patrol and armed gunmen near the warehouse. The Mexican media has dubbed them, "Los Monstruous," or The Monsters.

The area is considered a battleground for fighting between the Los Zeta and Gulf cartels vying to control drug trafficking routes into Texas.
