When flying PF we printed out maps and prepared in forehand. That was vital if you wanted to have a chance to return to Essex.
In CloD, like already stated, the map is so small and landmarks everywhere so I can't see any use for advanced navigation.
We don't have bad weather nor overcast so IR is of no use.
Even if we had bad weather air missions at that time was never executed unless good conditions.
Sure, advanced navigation is fun but for now useless imo.
