If it wasn't such an endeavor to yank the box and pull out the countless layers of insert trays in order to get to the cards on the every bottom, I'd be able to tell you for sure... But the cards have either mission numbers or mission icons in one of the corners... bottom right corner if my failing memory is serving me.
but I can spout off obscure rules to all sorts of game like nobody's business!
There's an icon of a lock with a number in it on the right middle of the text box for each card that was unlocked. If you find it on the schematics, which all have it, then it'll be easier to locate on the damage cards.
