CEP - Circular Error Probability
The CEP is a term normally associated with ballistic missile systems but can be applied to any ground to ground or air to ground missile system. The Circular Error Probability is a circular area around the target within which a warhead has 50% chance of landing. Obviously this concept is of little use unless a weapon is high yield or is carrying submuntions which cover a large area.
