Greatest Killstreaks In Call of Duty

I.M.S

The I.M.S, also known as the Intelligent Munitions System, is a five-point Assault point streak reward that appears in Call of Duty: Modern Warfare 3 and Ghosts. The I.M.S. is an anti-personnel system similar to the Bouncing Betty. It is a small box on the floor that fires an explosive shell up in the air which in turn then shoots an explosive straight down at enemies.
