Miss half of elite regiment units ! how to find them ?

I can't find most of regiments units in the game, only found Austria 1st emperor regiment, russian hussards. Where are the others one ? Moscow musketeers, Brandeburg Uhlans, les braves...... WTH ?

You sure you've added both codes I believe there was two of them in Imperial Edition. One on the manual and one on a seperate piece with one of those you have to scratch to see the code.

Yes, Maximus is right. I have the Imperial Edition and the units are in the game

thanks.
Just found out the answer : i bought standard edition and have only 5 elite units + the grande batterie. I'm still thinking why i gave money to sega .....
