I went up against Boba Fett's Slave 1 equipped with Proximity Mines and a Heavy Laser Cannon, along with cluster missiles, along with 2 Black Squadron TIEs. I managed to maneuver Dutch around the Slave 1 to disable him a couple of times before Dutch was destroyed by the Proximity Mine… Luke and Tycho made quick work of the TIEs and focused the cluster missiles and proton torpedoes on Fett and Tycho and Luke were critically damaged (2 Hull left), with Fett at three.

That's when the Slave 1 mismaneuvered and was hammered by Tycho (Who was at range 1 and was allowed an extra attack dice bonus) and he got 2 hits and a crit, and the card was the one that counted as 2 hull damage!!! Next time I'll go 200 point squads.

Don't know what's up with the white boxes.

You do realise that you need to hit a medium ship twice in the same turn with an Ion Cannon to affect it. The rule for this is in the handout you get with Slave-1 and the Millenium Falcon.
