we may be reading the rules wrong but it seems you put a leader in a space with no leader and move adjacent ships (with units) to the leaders location.
If this is right can you move a transport with a stormtrooper to 6 locations a turn to find hidden base? if not why? I don't see anything in the rules to stop this. if it works this way the imperials should find the base in 3 or 4 turns every game.
