This Tank of a Gun Drops 75 Rounds per Second

You need a gun that shoots really fast when trying to shoot down incoming missiles.

C-RAM is short for Counter Rocket, Artillery and Mortar. The gun in the video below is basically a land-based version of the 20mm Phalanx Close In Weapon System that the Navy on many ships to shoot down incoming cruise missiles.

It uses a 20mm M61 Vulcan rotary cannon (the big brother to a minigun) with an integrated radar-fire control system. With a rate of fire of 4,500 rounds per minute (75 rounds per second), it's capable of shooting down mortar and artillery rounds as well as rockets.
