What are the two types of range determination?

The correct answer identifies immediate determination as one of the two types of range determination. Immediate determination refers to the quick assessment of distance to the target, often utilizing methods such as laser range finders or direct observation techniques. This approach allows for swift decision-making in dynamic situations where time is of the essence, enabling gunners to quickly engage targets effectively.

Deliberate determination, the other type not chosen in this case, involves taking more time to assess the range, often utilizing tools like maps, range cards, or sophisticated calculations. This method is used when the situation allows for a more measured approach to ensure accuracy in range assessment.

The choice of immediate determination as the correct response highlights its significance in fast-paced operations where rapid engagement is crucial.
