Decapitation Rule (6.72)

[Proff3RTR]

I would go with the fact that the command as a whole would not hear anything from 'The Boss' for a while so command of the whole unit would divulge down to the next in command/highest survivng officer as per the 4th Ed rules, night time would not effect this in real life so it should not here.

if say for example you have not heard from the location where you know the commander was and prior to this there was a lot of gun fire etc from that location the next highest officer in the Chain of Command would take over, if when things were a bit clearer the real commander surfaced again he could retake command, no harm done etc.
