We have a government spy network that tells you exactly what resources and reserach the target has on hand.
We need a military specialist spy to find out what fleets the target has. This information is already available with some well timed infils and basic math. It’d be convenient to get it all in one place at one time.
To make it fairer the op report could be an estimate within +/- 10% for any given unit type, ie. you would have to run the op once for every unit type you wanted to check. Failures would show in the target’s news.
