Col MacGregor made the claim. I posted it yesterday. Search 🔦 still works.
It’s total BS. “Russia’s military casualties, the officials said, are approaching 300,000. The number includes as many as 120,000 deaths and 170,000 to 180,000 injured troops. The Russian numbers dwarf the Ukrainian figures, which the officials put at close to 70,000 killed and 100,000 to 120,000 wounded.” I’d say the US is more credible than Col. MacGregor.
