What is the primary purpose of the 'INVESTIGATE' call?

The primary purpose of the 'INVESTIGATE' call is to verify elements of Rules of Engagement (ROE), Positive Identification (PID), and coordinate forces. This call is essential in operational environments where the understanding and adherence to ROE are critical for conducting military operations. It ensures that all participants in the mission are aligned in their understanding of the legal and tactical parameters under which they operate.

By verifying these elements, the 'INVESTIGATE' call helps prevent potential fratricides and ensures that engagements against targets are both lawful and necessary. It facilitates a clear communication process for commanders and personnel on the battlefield, assuring that all actions taken are justified and coordinated appropriately with various units or assets involved in the operation.

In contrast, while gathering intelligence on the enemy, initiating direct attacks, and performing reconnaissance missions are all important aspects of military operations, they do not encapsulate the specific focus of the 'INVESTIGATE' call, which is centered on validation and coordination rather than direct action or intelligence gathering.
