on a side note, you realize theres a command to hit land bases using the map from a battleship or cruiser right? you just click on your map and the guns will automatically adjust to hit it.
yeah, ship guns (land mode) can click on the map for general area targeting, but they require visual to be more accurate. BB's can drop a hangar with one salvo, it takes a CA 3x.
You definitely want to keep the ships away from land for another reason, puffy ack, both manned and auto, if there's no way to take out the ship.
Can you lock the TGs into a specific routing that keeps them from visual targeting and not too close to shore?
Ship guns can id planes out to 12k (not sure how dar/icon settings will handle this) and can zoom into land targets fairly well (but not see GVs.)
I popped an MA goon in 5" guns - it was parked just over a crest about 12k away, I could see the cockpit... took a a while but eventually nailed it with he.
