you pointed to one example of a russian army retreat. using this one example to pass judgement on the entire russian army performance since the counterattack begain is misleading.
Don't think he is telling the truth. At least the part where he Claim the Russian army ran away. The frontlines are pretty well understood now backed by geo-located video evidence. Russian and Ukrainian battle maps pretty much agree on LOC (tho differ wildly on casualty counts). What we see...
UAF is facing heavy losses. Even if it's not reported in western media, the soldiers on the frontlines would know the real situation. It's understandable that many would choose to surrender.
could be ukrainian, could be russian. i'm not interested in making assumptions without proof. just like there is no proof that ukrainian air defenses shot anything down.
