Hu guys, we have a question regarding the downed AT-ST Act 2 card.

You had to secretly mark 2 buildings with a condition token marking possible entrances to the secret rebel bunker.
The card says that a trooper units gains "Action: Uncover entrance: Reveal a condition token on a piece of terrain that your unit leader is in base contact with.".
Our question is: Do you have to be in base contact with the piece of terrain holding the condition token or the condition token itself in order to flip the condition token and reveal wich building is the secret bunker?

Also if i recall correctly, infiltrate is forbidden but scout is allowed, right?

Thanks!

The trooper has to be in base contact with the piece of terrain that has the condition token. The token per se is just for marking which pieces of terrain were selected and which one is the entrance.

For your other question, you're right, there's no rule preventing you from using scout on those scenarios.
