The English-language gap in Russian special-forces history

Are there reliable English-language books on Russian special forces?

Many published accounts are uncritical, while the stronger translations discussed had not yet been published.

English-language reading on Russian special forces comes with a warning. Many published accounts are said to repeat familiar stories rather than test them critically. The stronger translations mentioned here were not yet publicly available. Translation and publication access limit what English-language readers can assess; they do not show that the Russian record itself lacks depth.
