Fill in the circular error, in feet and meters, for CAT I?

For Category I (CAT I) in field artillery, the circular error is defined as a 50% probability that a round will impact within a certain radius of the intended target point. The correct range for CAT I is characterized by a circular error radius of 0-20 feet, which corresponds to approximately 0-6 meters.

This specific designation means that CAT I is designed for missions requiring high accuracy, and the limited radius emphasizes precision in targeting. The operational capability associated with this category is particularly critical in situations where collateral damage must be minimized, such as in urban environments or when engaging high-value targets.

The other ranges provided in the options exceed the precision parameters set for CAT I, which signifies that they do not accurately represent the definition and expectations for circular error in this target category.
