SAROPS supports how many SRU types?

• A. 4
• B. 3
• C. 5
• D. 2

Answer: (A)

The concept being tested is how SAROPS categorizes the resources that perform searches. SRU types are the categories that define what kind of asset is doing the searching, and each type has its own performance characteristics that SAROPS uses to shape search patterns and probability calculations. SAROPS standardly supports four distinct SRU types, which is why four is the correct count. This setup lets planners combine assets like air and surface resources in a way that keeps the modeling consistent and yields meaningful search effectiveness results. If you considered fewer types, you’d be underrepresenting the variety of assets typically used; more types would add complexity beyond what SAROPS standardizes.
