The rules state that if a player does NOT have a leader with tactics values in a system, they can add one leader from their pool to the system for the combat (basically the combat equivalent of opposing a mission). However it makes mention that should multiple leaders be present, you use the highest value for each theater of combat.
Now, does this mean that if a leader happens to be on this system from a previous mission or attack, a player can NOT add a new, additional leader during this step of combat (except in the case of a special ability possibly allowing such an action)? Only the already present leader(s) would contribute their tactics value(s), right? This is how I'm reading this rule, but the multiple leader clause makes me wonder.
Thanks all!
P.S. Love this game so far!
