Sorry, but if you could move from unit to unit to see with your own eyes what's happening in 3D, it would violate the entire design of a game like LG.
On the 2d map you will see units that your CiC can
not see even when you have the camera locked onto the CiC. I'm saying you should be able to see those same units on the 3d map as well as the 2d map.
The way it is (and should be), in full FoW you see what your CinC sees.
OK, that's fine if that's what you want, but as of now that does not happen, on the 2d map you see
more units than your CiC can see.
If you want more info, you have to send an aide and wait for a report, or move to that area and take a look for yourself.
You can see on the 2d map, any unit that your men can see, that's why you send out Cav on scouting missions - to spot the enemy, which will then be shown on the 2d map.
Look at the two pics above, the Russian units on pic2 are spotted by the scouting Cav, not the CiC, but you get to see them on the 2d map, so why should you not be able to see them on the 3d map ?.
If we go with what you say the ONLY units shown on the 2d map will be those DIRECTLY seen by the CiC, again, that's fine if that's what you want, but it is not the case now.
