In NYGM the sonar doesnt give range anymore so that is great.But just popping up periscope and then back to nav map and target new location is marked and easily tracked allowing a bit too accurate ships course from far away.What if you leave the sonar dotted line but remove only the surface ship icons?
When submerged and pressing identify the SO speaks but the WO cant as he is now inside the sub.But submerged with scope up and the target icon still gets marked on map as if the WO is inputting this info still.
Removing the surface map icons and to plot course on surface you ask WO for nearest visual contact,he gives bearing and range and you mark on map with info given.Wait a bit and ask again and mark etc.Yes WO is still too accurate but instead of just marking the target box for location you must use the tools and take his bearing and range and then mark.Its a bit more involved.
Then when submerged the WO can no longer give his super accurate range as he is inside of sub and with surface ship icons removed you are now on your own in regards to range.....which some say doesn't matter
