I was searching for info on the Web about Freikorps units and Reichwehr units for a what if scenario starting after a " Polish defeat " at Warsaw and Lenin declaring that the Révolution had to be exported in Germany, the final goal.
But i saw that actually that Baltic States like Ukraine had a chatotic period where Reds entered Révolution and that in their wake some Bolchevik units followed, then ensued a fight between Latvians/Germans (4/5 germans in Latvian Army) and that Freikorps Units were very active there Baltische Landwehr.
Actually this is different from the Official declaration of War in the game
I don't know what is the OOB for the Latvians in the Game but the order of Events should be perhaps changed (in the next months) so as like Ukraine, we have a more correct chains of Events and introducing the Freicorps and German Units (VI Reserve Corps) which intervened and liberated Riga.
I will look more closely to what happened to improve the game in the Baltic States and introducing more details.
