I know that this is a hobby-horse of yours, and I accept that contemporary Russian officer academic standards had been recognized as wanting for many years, but . . apart from BELIEF, do you have any RUSSIAN sources, which say (in so many words): `Our artillery equipment, personnel and doctrine are all rubbish (compared with other European armies) so we must have lots more of it.`
After all, artillery was the most expensive component of an army.
Also, just having MORE guns (and vehicles, horses, ammunition, arsenals, artificers etc) would not necessarily be effective on the field of battle.
Was there a deliberate Russian doctrine of quantity over quality? If so, where was it laid down?
