La Línea ("The Line") is currently the leading faction of the Juárez Cartel originally designed to be one of the cartel's enforcer units set up by a number of former and active-duty policemen, heavily armed and extensively trained in urban warfare. Their corrupt "line" of policemen were set up to protect drug traffickers, but after forming an alliance with Barrio Azteca to fight off the forces of the Sinaloa Cartel in 2008, they established a foothold in Ciudad Juárez as the enforcement wing of the Juárez cartel. La Línea has also been involved in extortions and kidnappings. As of 2021, La Línea has formed an alliance with the Jalisco New Generation Cartel in Ciudad Juárez to fight off influence and incursions from the Sinaloa Cartel.
