What does CEP stand for in guided weapon terminology?

In guided weapon terminology, CEP stands for Circular Error Probable. This term describes the accuracy of a guided weapon system in terms of the radius within which a certain percentage of rounds will fall. Specifically, it measures the precision of the munition's delivery, indicating that in a circle with the radius equal to the CEP, a specified percentage of the rounds (commonly 50%) will strike. This metric is crucial for evaluating the effectiveness of precision-guided munitions, as it provides a statistical basis for understanding their capability to hit a target accurately.

The other choices do not correctly define CEP in this context. While "Common error probability" and "Critical engagement point" suggest concepts related to errors or targeting, they do not align with the established usage of CEP in military terminology. Similarly, "Central effective position" does not correspond to the definition of CEP and lacks relevance to guided weapon accuracy metrics. Understanding CEP is essential for evaluating the reliability and efficiency of precision strike operations in modern military tactics.
