Well, I will read this whole thread, but my initial thought is that what official sources or leaders say about what soldiers actually do in any army in any time is close to useless/meaningless information

Do you know soldiers?

Their slaviness is over-rated. If their leaders are competent their interest in their soldiers' slaviness and standardization are more for outer show and inner unity and efficiency than for interfering with what works.
In other words, what would you expect the officials to say? The official line.
