The overall 'God' view is not that implausible if you consider you are supposed to be BN or BDE level commander. What is unrealistic is the ability to quickly 'reach' down to squad level and take action on something known to another unit that would be operating on a different comm net.
If you want to simulate a 'more realistic' C&C situation, use the game function to make way points for your subordinate (below A0) formations and turn them over to the AI. Limit yourself to only changing the way points every three turns (6-9 minutes simulated RL time).
For a battle simulating an EW environment, turning the units over to AI and increasing the 'turn control delay' could simulate EW C&C effects.
