Hello,
I've searched in the forums by I didn't found this question...
If the Imperial player enters a system with only space units, the Rebel player don't have to tell if the Rebel base is that location, even if it is.. But, if the Rebel player plays Rapid Mobilization, decides at the end of command phase to move the Rebel base due to the threat of Imperial Fleet... due to this, Ships and ground units in the Rebel base space are moved to the system where the rebel base was... and then there are imperial and rebel units in the same theater... Does a battle begin right in this moment although is the end of command phase? Can players add a availabe leader to the fight?
Regards.
