Here is an idea regarding "relative spotting" please keep in mind I am not any sort of expert so I am not completely sure this would be realistic:
Unit have two levels of influence from commanders
1) as modeled in the current version- morale bonus, combat bonus, etc.
2) a "contact level" influence - meaning the commander must be within a certain distance in order allow the player to "see" what the unit sees. For example a crew bails out and is outside this "level 2" command range. All info the bailed crew sees is not reported, however a marker indicating the last know location is given(much like how enemy contact is shown) unless another unit within this level 2 command range has LOS to the bailed crew.
The player in this situation would not be able to command the unit until it is within the "level 2" command range. This could be applied to all units where the range of this level 2 command factor is relative to the units experience, unit type (recon unit is always under level 2 command radius).
Just my $.02 worth. Just wanted to see if this is feasible.
