Which of the following is NOT considered one of the four tasks of ISR?

The correct choice is targeting, which is not one of the four primary tasks of ISR (Intelligence, Surveillance, and Reconnaissance). The fundamental tasks of ISR focus on collecting information and data relevant to understanding the operational environment and enemy activities.

Surveillance involves continuously observing an area to detect and track the movements of objects or personnel. Reconnaissance encompasses the focused gathering of information about the enemy, terrain, and other critical factors to support tactical decisions. ISR synchronization refers to the integration of various ISR capabilities to ensure they operate effectively together, maximizing their collective output.

Targeting, while related to the broader context of military operations, specifically pertains to the process of selecting and prioritizing targets for military engagement. This task falls outside the essential frameworks of ISR, which emphasize information collection rather than execution or engagement strategies. Thus, the distinction between ISR tasks and targeting helps clarify the specific roles and responsibilities within military operations.
