Side A is sailing in open waters.
Side A and Side B are hostile to each other.
Side C, a civilian (or other nation), and is NEUTRAL to Side A, but FRIENDLY to Side B.
In fact, Side C currently begins the game with a trawler (or other intelligence ship) about 10 miles away from some of Side A's ships, say a carrier group.
For game purposes, the Side C trawler intends on following the Side A ships, while providing constant updates as to their position to Side B.
So, is there anyway to do that in the game? I know that I could use Rotating Reference Points to move an area to allow a unit from your own side to a relative position, but is there a way to make it happen with a unit from another side controlled by AI? It isn't critical, but it could be a useful tool.
In my experience, I believe that with satellites, and confined waters like the Persian Gulf, or the Straits of Hormuz, there is always lots of traffic, and it's really hard to hide a carrier group, etc. So, this procedure/method would be a nice means to be able to provide intelligence to one side (if needed) for game purposes.
