El Chapo's once mighty cartel is now operating in the shadow of the CJNG.
He said: "The federal Mexican forces have far more military capacity and firepower than the cartels.
"The issue is that they are stretched thin across the county containing the 'criminal insurgency' taking place and now having to respond to the effects of the Covid-19 pandemic in Mexico.

"Still, the Sinaloa Cartel is stronger in some of its core territories such as Culiacan and extended regions."
I’ve been tracking propaganda videos for some years now with their kill teams/enforcers getting more and more sophisticated in terms of training and equipment

Hangings on motorway bridges have become a trend.
In fact nothing seems to be off-limits.
In January, video emerged of the CJNG's glamorous hitwoman a La Catrina gasping for air as a soldier tells her to "relax" and "You are going to be fine. Try to hold on."
La Catrina, whose real name was Maria Guadalupe Lopez Esquivel, died after the shootout in the city of Tepalcatepec, where Jalisco New Generation Cartel (CJNG) gunmen opened fire on authorities for dismantling one of the group's roadblocks.
