Cártel de Jalisco Nueva Generación (CJNG) is presently under attack in Colima State by the Mexican Army. At this point they have cleared Colima City, Tecoman of the Sinaloa Federation (CJNG) and Los Caballaros Templarios have moved in to fill the void. The Army also moved into Manzanillo, but not as hard and CJNG still retains a presence there.
Ruben Osegevera Cervantes (El Mencho) runs CJNG and his headquarters in the Autlan de Navarro and El Grullo area of southwestern Jalisco. It is also being heavily pressured by the Mexican Army (SEDENA).
It's not really news to the people in Guadalajara where literally ALL of the narcos with any stroke at all left town about a month ago in anticipation of rough times. Some went to homes in San Antonio, Texas (where many of the Guadalajara narcos maintain residence), others with warrants for their arrest either went to Costa Rica or over the hills to Puerta Vallarta. They plan to return home after February when the Mexican Army will be discontinuing its offensive in that area.
There are two principal factions of the Sinaloa Federation in Guadalajara. CJNG is run by El Mencho. He's the one being hit. Ismael Zambada Garcia (El Mayo) is not being pressured. He is more closely allied with Joaquin Guzman Loera (El Chapo) than El Mencho is.
