The Centurion Counter Rocket, Artillery, and Mortar, abbreviated C-RAM or Counter-RAM, is a system 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 a land version of the the Phalanx CIWS radar controlled rapid-fire gun for close in protection of vessels from missiles.

In Battlefield 3, the C-RAM functions as the American anti-air emplacement. It is typically placed near the runway at the main base (US Deployment), watching the nearby airspace but generally out of sight of the rest of the map. The Russian counterpart to the C-RAM is the Pantsir-S1.
On maps where the USS Essex functions as the US airbase, the Phalanx weapon system is also referred to as a C-RAM for statistical purposes. It is also used in Damavand Peak in Rush mode, located at the first U.S. base. Other examples include Operation Firestorm, Caspian Border, and Bandar Desert.
Various patches have been made to adjust damage to infantry and air vehicles. A patch also increased the projectile velocity, which increases its range and decreases target leading.
A patch made to many maps removed or relocated the C-RAM and Pantsir. One notable change was to Noshahr Canals, where the C-RAM could fire on much of the Conquest maps, killing infantry as far away as Train Yard.
- If someone watches the C-RAM shooting from a third person view, they can see that it fires with a very slow rate of fire. This can also just simply be the extreme speed of the bullets which are fired so fast, that only every 20th shot can be seen with the human eye. This also occurs with the Pantsir-S1.
- The C-RAM and Pantsir S-1 are almost always positioned behind hills or mountains, making them only effective against close-by attack aircraft. This is to promote the enemy not 'spawn killing' and allow the C-RAM/Pantsir to effectively take down aircraft closeby but not from extreme distances.
- Kills obtained by using the Centurion C-RAM or the Pantsir-S1 count toward stationary turret awards and medals, not mobile anti-aircraft vehicles.
- The 1.04 patch gave the C-RAM and Pantsir S-1 Air Radar.
- For consoles, the left analogue stick can be used to traverse your horizontal aim more quickly, and is useful for attacking targets that pass directly overhead.
