What are the various scale values that the operator may select on the BSD?

The correct answer identifies the specific scale values that an operator can select on the Battle Staff Display (BSD). The range presented — 800, 400, 200, 100, 50, 25, 10, 5, 3, and 1 KM — reflects the nuances required for effective air defense management. These values allow operators to view and analyze situational data at different levels of detail, essential for making informed decisions regarding threat engagement and resource allocation.

The use of smaller increments, down to as low as 1 KM, enables precise tracking of threats and evaluating the operational environment in high detail, particularly important in dynamic combat situations. This flexibility in scale enhances situational awareness, which is pivotal for responding to fast-moving aerial threats.

The other options reflect either a limited set of scale values or different measurement units that do not provide the comprehensive range necessary for air defense operations. For instance, values such as 1000, 500, 250, and 100 may not offer the granularity needed in certain tactical scenarios, while values like 1, 2, 5, 10, and 20 KM lack the higher scales required for broader situational assessments. Thus, the correct answer is accurately aligned
