1. ANSWER
No exact verified figure exists specifically for "Russian soldiers" (ethnic Russians or Russian SFSR), as WWII records track Soviet Red Army casualties. The official Russian Ministry of Defense estimate (Krivosheev, 1993) is 8,668,400 Soviet military irreplaceable losses (dead, missing, POW deaths).1 Ethnic Russian losses (excluding POWs) were approximately 5,756,000.2

2. EVIDENCE —
- Wikipedia (updated as of 2026): Krivosheev's 8,668,400 Soviet military dead/missing; official Russian total losses 26.6 million. Higher estimates (e.g., Zemskov 11.5 million, Mikhalev 10.9-13.7 million). Russian SFSR military ~6.75 million per Erlikman (disputed, part of 10.7 million total).13
- National WWII Museum (current): Soviet military 8.8-10.7 million.4
- Meduza (May 9, 2025): Krivosheev >8.6 million Soviet army losses.5
No single source verifies "Russian soldiers" precisely; figures often conflate with Soviet totals.

3. CREDIBILITY — 8 (estimates consistent on ~8.7 million Soviet military; "Russian" imprecise without ethnic/RSFSR breakdown).

4. CONFIDENCE — 10 (overwhelming consensus on Krivosheev as authoritative Russian official figure).

5. BIAS — CENTER (academic, museum, official Russian MoD sources).
