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.
NM...found out from Capn Darwin that if you roll 9 on the Chaos table, you get an extra support mission and you roll 2d6 and consult the Support column to find out what fire support mission you get.
So that column is not specifically mentioned in the manual.
