The thing is if you do cannons the Arrow Knights will just kill them very easily.
You cannot do Cossacks because the Eagle Runner Knight is a Dragoon and will kill your cavalry.
And the Ototin Slinger just kill Cav. Archer, Heavy Infantry (So kills both Musketeer and Halberdiers) and they also kill Strelets because they do more damage and outranges the Strelets.
I do agreed with @Khorix9572, if Russia had a proper Skirmishers unit, they could just kite and kill the Slingers and the Eagle Runner Knights, and have some chance.
But Strelet just get kite away and die, since because their range is so bad, they don’t kill neither the Slingers neither the Eagle Runner Knights.
