Mexican Drug War became the starting point of the war between the government and the drug cartels. Calderón escalated his anti-drug campaign, in which there are now about 45,000 troops involved in addition to state and federal police forces. In 2010 Calderón said that the cartels seek "to replace the government" and "are trying to impose a monopoly by force of arms, and are even trying to impose their own laws." As of 2011, Mexico's military captured 11,544 people who were believed to have been involved with the cartels and organized crime. In the year prior, 28,000 individuals were arrested on drug-related charges.

He survived the war for the control of the department of Casanare between the Bloque Centauros and the paramilitary group of Héctor Germán Buitrago ("aka" Martín Llanos), and then was blamed as the author of the death of his own boss, Miguel Arroyave by Salvatore Mancuso, who declared Guerrero a military target. Following the death of Arroyave, Guerrero became one of the leaders of the divided factions of Bloque Centauros.
