But seriously. They're doing an 'Advent Calendar' for December, with each day offering up a new digital download for purchase. The downloads are in the $4-$5 dollar range, just right for an impulse purchase. December 3rd's was of note for me, because it contained a new Tau Empire formation, one that just so happened to match exactly the contents of a large box set GW just recently put up for sale.
How convenient...
The Firebase Support Cadre has to contain an XV104 Riptide and two squads of three XV88 Broadsides, though the drones are optional. It costs no additional points, and curiously, can be taken in addition to Allied forces, without requiring the player to run a core Tau force; you could, if you wanted (and could somehow find the points for it all), run a Marine army, with Inquisitor warlord, Allied with Imperial Guard, backed up by a Firebase Support Cadre. 40K is getting weird, guys.
