From MP.net:
Army troops seized 400 pistols and rifles, 500,000 bullets, 165 grenades, several grenade launchers, six heavy machine guns and an anti-tank rocket launcher.
Assistant Attorney General Marisela Morales said the arsenal “is the largest in the history of Mexico.”
Hollywood bling. Note the two revolving multi-shot grenade launchers.
That is some serious firepower!
