Historically, cavalry was tanks of RCW. Both sides relied heavily on it as mobile breakthrough and shock troops. Almost all memoir sources tell about the devastating effect cavalry charges had on low-quality infantry that was commonplace during the war, even if said infantry was entrenched and supported by machine guns. Many battles, in fact, especially for the whites, looked somewhat like "after the initial firefight, cavalry performs a flanking move, the enemy panics, starts running and is ridden down". Both red an white generals recognized the tremendous importance of cavalry. Red military theorists attributed their victory largely to Budennyi's use of large cavary masses, later leading to Tuhachevsky's mobile war doctine that saw use in WW2. And white generals, most notably Wrangel, named a faliure to create proper white cavalry and thus having to depend on unreliable cossack units in critical situations as one of the main reasons of defeat. Even tachanka became legendary and earned it's place in songs

I am curious if RUS really models this.
