How can i create that?

Seems like its always the same nation both you and your opponent.

I thought the last patch...fixed that.
oh well...
Load the Editor, implement what you want.
To include the choice of armies & who plays them, even an AI vs AI is possible.
You can save them in your Documents/My Games/Panzer Corps 2/Scenarios or Multiplayer folder.
Create them if they don't exist.
You can play the scenarios, random or otherwise from the Editor.
This Editor is one of the best I have ever used for this type of job.
You can even 'import' the PzC 1 scenario maps to work with.

it says Players Faction in the drop down menu...

I don't want anything custom.. just a random map with Germans vs Americans.


They have all those new good game modes like defense etc.. but you can't choose different nations lol

Per the Editor, you don't have to customize anything if you don't want to.
Just load, click random map under 'Tools' & 'Play'.
However, if you want U.S. vs Germans...just assign them.
Until the 'devs' change this method (no need to, considering how easy this works imho), this is the only way.
