Hit on a good point being the focus on 'reclaiming' territory like crimea and along the Eastern border regions is a mistake and just provides more lives for the meatgrinder.

I've also heard from more pro Ukrainian sides, that the Russians seem a lot better on defence just as the Ukrainians were good at defence leading to the same issue of massive loss of equipment and lives for extremely little gain and this is a lot of veterans lost so the 'fresh numbers' don't have the field experience to not fall for the traps veterans know to avoid.
