Which descriptor is linked to the combination 72 ISRS and 75 ISRS?

• A. Expeditionary
• B. Global ISR
• C. Both 72 ISRS and 75 ISRS
• D. ES for EA effectiveness

Answer: (C)

In this context, descriptors identify how items relate to each other or to their capabilities. When a descriptor is linked to a combination, it means that descriptor applies to the entire pair, not just one element. Here, the two items are 72 ISRS and 75 ISRS, so the descriptor that correctly reflects their shared association is the one that states “Both 72 ISRS and 75 ISRS.”

If you used a descriptor like Expeditionary, it would imply a deployment context for a single system. Global ISR describes coverage or scope for an item, not the linkage between two items. ES for EA effectiveness points to electronic attack effectiveness, which isn’t about the relationship between the two ISRS entries.
