Just as with the old Tactica, this could be the thread where we discuss tactics using the 13th Company. Please add your thoughts.
I'm up for a tournament the coming weekend and believe myself to have got a few things right, at least. I usually go for large units nowadays. Even my fire-decoy Wulfen Unit have been beefed up to eight models, to be able to weather the fire.
The idea is to sprint up in the middle with the Wulfen (or up a flank if it's too flat ground in the middle of the field), getting the opponent to either split his fire between lots of units (I'll have about four units halfway across the table after the first turn), or only concentrate on one, thus giving the other units a worry-free ride into combat.
I always use a Fenrisian Wolf unit at least 10 wolves strong. Their job is to run into whatever screens the enemy firepower units may have. (Last game they ran into a Nurgling horde, and then blocked half the Death Guard army from shooting altogether.) After running straight into the enemy wall, they will usually hold anything up for at least a turn or two.
