What are the black trucks in the presidential motorcade?
Have you ever wondered what all those extra SUVs are in the Presidential or VIP motorcades? You know the ones with blacked windows that no one gets in or out of. Well, wonder no more. They have a 6-barreled 7.62mm mini gun. They fire over 4,000 rounds per minute. The wipers need to be run to remove spent casings when the weapon is firing.
