Death's Head Hussars

I've about to pre-order the Special Forces edition from GAME. It tells me I'll get an exclusive unit called the Death's Head Hussars available to Prussia... what does this mean? That you only get this if you order from GAME? Is this in addition to the 6 special forces edition units? Would I get a different 'exclusive' unit with other stores?

Yes you would get the USS Constitution from play.com and an Amazonian female rifles if you get it from (funnily enough) Amazon.com.
