Question: House Rules for Scouting

[Captain Al]

Guys, 

Thanks for the replies. 

I was thinking for cavalry that all units need to be within the command radius of their Brigadier.   That way it limits scouting to brigade strength.   Not that many brigades and not worth losing a whole brigade raiding for VPs.   But still allows for necessary scouting on a large map.
 
As far as leaders (and their field radios), something similar that leaders have to stay within a certain range of one of their units.   I thought there was a rule about how far skirmishers could go from their parent unit?
