Wait - so these "leaks" are actually from the US DoD and NOT from the Kremlin?

That's a laugh.

You have it 100% backwards - it is Ukraine who has been suffering the staggering casualties. The US DoD does not know shit. They have been telling us that Russia was running out of missiles and ammo since July 2022. How'd that turn out?

This is just pure western propaganda, and shame on you for spreading it.
