For the second time this month, officials in Mexico have seized a "narcotank" - a regular production vehicle that a drug cartel has turned in to a battle vehicle.

The latest "narcotank" was found Friday, after a clash between police and gangs of rival gunmen in the western Mexico town of Mezquitic, according to a report in the Latin American Herald Tribune.

Reports said the guts of the "narcotank" are a Ford F-series Super Duty truck. It had been customized with steel plating with ports for guns or other weapons, a rotating turret and a fold-up battering ram. No weapons were in the vehicle when it was found, according to the Herald Tribune report.

Earlier this month, the Mexican army captured another armored vehicle, according to a report on BusinessInsider.com. That tank, dubbed El Monstruo 2011, was capable of going 68 mph and could carry 12 people behind its armor, the report said. It was seized in Ciudad Meir, where the Los Zetas gang has been battling over drug business with the Gulf Cartel, their former bosses, BusinessInsider said.

The website InSightcrime.org reported in April that traffickers are increasingly turning to armored vehicles.

Besides armoring vehicles, traffickers have also made their own submarines. Check out what VBS.TV found at a Colombian naval base last year.
