Los Zetas served as the hired private mercenary army of the Gulf Cartel.
Los Zetas is a Mexican criminal syndicate and terrorist organization, known as one of the most dangerous of Mexico's drug cartels. They are known for engaging in brutally violent "shock and awe" tactics such as beheadings, torture, and indiscriminate murder. While primarily concerned with drug trafficking, the organization also runs profitable sex and gun rackets. Los Zetas also operate through protection rackets, assassinations, extortion, kidnappings and other illegal activities. The organization is based in Nuevo Laredo, Tamaulipas, directly across the border from Laredo, Texas. The origins of Los Zetas date back to the late 1990s, when commandos of the Mexican Army deserted their ranks and began working as the enforcement arm of the Gulf Cartel. In February 2010, Los Zetas broke away and formed their own criminal organization, rivalling the Gulf Cartel.
