Actually, this is kinda old news by now, but Privateer Press not only provides Khador players with an upgrade kit to change a unit of IFP into Black Dragon Iron Fang Pikemen, no, they also provide an official statcard for an alternate UA. In summary, the main differences are a different "mini-feat" and an ability replacing Relentless Charge.
The Khador forums are abuzz with praise, and I did join in - at least, I ordered all the additional trooper blisters necessary to max out the two IFP units I already had, and soon I'll be fielding two units of them. Well, as soon as they are painted, at least. ;)
Gladly, I've found a fellow german painter and blogger who'd be willing to put with my models. :)
Okay, that's all. Just some rambling about "new" units. Farewell!
