I am interested in the performance of the Russian military during the Seven Years' War, what were their strengths and weaknesses? How was the performance of traditional Russian units vs non-traditional Imperial units (eg. Cossacks, Bashkirs, Kalmyks etc.). I know that it is a stereotype that the Russian army outnumbers everyone and wins because of that, but was there any truth to this in this war, or did they show other prowess?
I haven't been able to find much up til now aside from Suvrov showing great performance (although I don't know what kind of units he commanded), and the Russian army having poor training and logistics, with many southern units only scoring between 15-35% in a marksmanship trial.
