Sounds like cartels have entered the maquiladora business.
The Mexican Navy has discovered a factory where cartels apparently made fake military uniforms, according to the BBC and other media outlets.
The factory was in Piedras Negras, a border town in the state of Coahuila, where maquiladoras — assembly plants — are the mainstay of the economy.
The Navy seized military pants, shirts, body armor, presumably to be used by cartel hitmen and commando squads.
