For anyone with any play knowledge of this game...
One of the Player Aid Cards has a section that lists the Chaos chit results. The third (and final) column on that player aid card is headlined (I think) Support. What's it for? It seems to list types of fire support, but I don't see any reference in the rules to it.
I can't find the online rules to do a search either, so I only have the paper version - but I've been through it and really can't find anything on it.
