Bottom left card has been spotted by a few others and seems to allow you to place bombs during the setup forces stage of the game. Looks like "any number" starts off the third line of text. So...
Sabine crew and extra munitions would allow you to place up to six sets of cluster mines or connor nets on the board before the game even starts? Not sure if extra munitions will work, depends on the exact card text. Even three sets would be insane. Especially with Sabine around to make them really sting.
