Shame we can't have ski troops actually using skis on the battlefield..
Of course not. Its not need at all.
Well on the Russain front Cossacks still rode horses
I'm sorry, but that's not the Cossacks in our reality
Cossacks is a militia from Southern places of Russian Empire (Central Ukraine and Don area) in 17th Century.
And somthing like police in last years of Russian Empire. Not USSR, Not WWII on Red Army side.
as did some German Units at the start ..same with the Polish..so no not units sent to the future..
In WWII its a light _infantry_ that uses horses to movement purposes. Not to ride on the battle field.
And Germans have more cavalary at end of war than at start
Not German Cossacks of course
In game this units for USSR already is present with uniforms and rosters. Horse movement on operational phase before battle.
