It's very difficult to give accurate information when in GVs. You can't just say "by the red barn" because there are an infinite number of identical red barns. The entire terrain is just a collection of unnamed repeating features that all look the same so it is difficult, or often impossible, to single any location out. You can only hope to reference position to friendly icons, but due to the limitations of screen resolution, it is often hard to tell which direction the friendly is pointing to give him an o'clock heading to the target. The only place there are actual location names is in the town. The streets are named and supposedly you could say the enemy tank is at the corner of Hyteks and Suds, but I've never seen anyone ever do that. Of course the addition of the Storch has improved GV location greatly.
However, the OP is right: there's lots of utterly useless information given. My favorite is "There's a tank over there in those trees".
