I just got the Race for the Galaxy: The Brink of War expansion, which I haven't played yet. It comes with some additional Takeover markers. These two markers look like "temporary defense gained by discarding cards" markers:
I can't find the card that gives this power. The rulebook states they are for Rebel Pact:
Two counters are supplied to track a player’s total possible Military on defense (for use with Rebel Pact).
But Rebel Pact is part of the Rebel vs. Imperium expansion. In Settle phase, it gives
+2 defense against a [takeover] for each... (Rebel military world) in your tableau; +1 defense for each other [military world]
and the Rebel vs. Imperium expansion already comes with markers for tracking Rebel Pacts defense:
What card are these markers used with? What do they mean?
