Really? It's that hard to figure out? This gringo says "Take your pick":
- The Sinaloa Cartel
- The Jalisco New Generation
- The Gulf Cartel
- The Los Zetas Cartel
- The Beltran Leyva Organization
- The Juarez Cartel
- The Knights Templar
- The Tijuana Cartel
I'm surprised the pickup truck didn't come fully equipped...
