U.S. Soldiers conduct a live fire test from C-RAM in Iraq and Afghanistan.

Counter Rocket, Artillery, and Mortar, abbreviated C-RAM or Counter-RAM, is a set of systems used to detect and/or destroy incoming artillery, rockets and mortar rounds in the air before they hit their ground targets, or simply provide early warning.

C-RAM is effectively a land version of weapons such as the Phalanx CIWS radar-controlled rapid-fire gun for close in protection of vessels from missiles.
