What is the circular error for CAT IV in meters?

The circular error for CAT IV is defined as the range within which 50% of the impacts will occur when a particular munition is delivered. For CAT IV, this circular error radius is specifically recognized to be between 31 to 91 meters. This classification helps to quantify the accuracy of munitions based on their design, type, and the systems used for targeting.

The boundaries of this range demonstrate the degree of effectiveness for munitions classified in this category, which may include those designed for more significant area effects rather than precision strikes. Understanding this parameter is critical for FIST personnel as they plan and execute fire missions, ensuring they account for the potential dispersion of rounds and its impact on the battlefield.

The other options present ranges that do not align with the established definitions and standards for munitions accuracy within the different categories. Recognizing the correct range is essential for mission planning and risk assessment in fire support operations.
