Mexico's fastest-rising cartel, the Jalisco New Generation gang, has a reputation for ruthlessness and violence unlike any since the fall of the old Zetas cartel. In parts of the country it is fighting medieval-style battles, complete with fortified redoubts, to expand nationwide, from the outskirts of Mexico City, into the tourist resorts around Cancun, and along the northern border.
Jalisco so likes violence and heavy armament that U.S. prosecutors said its operatives tried to buy belt-fed M-60 machine guns in the United States, and once brought down a Mexican military helicopter with a rocket-propelled grenade.
