So basically as I understand it. In the absence of specific Intel on a target/area it can come down to;
Find blob with A/G radar,
slave TGP to blob for VID, and
attack or not (based on ROE).
I doubt there is a situation where you would be authorized to attack an unknown/unidentified "target" these days.
Still, a very useful tool for searching a wide area fairly quickly to help focus other sensors in our fictional conflicts.
