In 1997 the Gulf Cartel began to recruit military personnel whom Jesús Gutiérrez Rebollo, an Army General of that time, had assigned as representatives from the PGR offices in certain states across Mexico. After his imprisonment a short time later, Jorge Madrazo Cuéllar created the National Public Security System (SNSP), to fight the drug cartels along the U.S.–Mexico border. After Osiel Cárdenas Guillén took full control of the Gulf Cartel in 1999, he found himself in a no-holds-barred fight to keep his notorious organization and leadership untouched, and sought out members of the Mexican Army Special Forces to become the military armed-wing of the Gulf Cartel. His goal was to protect himself from rival drug cartels and from the Mexican military, to perform vital functions as the leader of the most powerful drug cartel in Mexico. Among his first contacts was Arturo Guzmán Decena, an Army lieutenant who was reportedly asked by Cárdenas to look for the "best men possible." Consequently, Guzmán Decenas deserted from the Armed Forces and brought more than 30 army deserters to form part of Cárdenas' new criminal paramilitary wing. They were enticed with salaries much higher than those of the Mexican Army. Among the original defectors were Jaime González Durán, Jesús Enrique Rejón Aguilar, Miguel Treviño Morales, and Heriberto Lazcano, who would later become the supreme leader of the independent cartel of Los Zetas. The creation of Los Zetas brought a new era of drug trafficking in Mexico, and little did Cárdenas know that he was creating the most violent drug cartel in the country. Between 2001 and 2008, the organization of the Gulf Cartel and Los Zetas was collectively known as La Compañía ("The Company").
