before you ask narco tanks really exist
wikipedia will explain better than me.-
A narco tank (also called rhino truck, or monstruo (Spanish for “monster”) ) is an improvised armoured fighting vehicle built from a truck, which combines operational mobility, tactical offensive, and defensive capabilities. These vehicles are used by Mexican drug cartels in the Mexican Drug War.  About 20 of such armoured trucks have been seized in Tamaulipas state alone.
