Russia has claimed to destroy more of every system than the west has sent, before they were even fully sent. Visually confirmed loss data has proven that Russia lies consistently about loss ratios vs Ukraine and number of systems and personnel lost, and have been throughout the entire war. Ukraine lies to some degree too, but no where near as much the Russians lie. You can believe me if you want, and I know you probably won't, but for everyone else reading, anyone telling you to take the russian claims as truth (or Ukrainian for that matter, or anywhere that isn't open source and/or transparent about its methodology with plenty of proof to back it up), is probably lying to you, either willfully or ignorantly.

No but they didn't claim the mass graves in bucha either so i am reluctant to trust their silence
