Sorry to be a downer (no pun intended) but the news of Russian high value equipment being lost does not translate to victory in battlefields that is being sought after more by the public. The Ukrainians just lost Avdiivka (in part thanks to Republican stonewalling aid package to Ukraine) and there is reports of armoured assaults in Robotyne, a major village which Ukraine retook in their last counteroffensive.
Russia is willing to take more losses, because unfortunately the Russians are too steeped into Putin’s propaganda.
Public morale and perception is as important. If Western public feels that results are not worth the money, they will demand or elect politicians who will withdraw support to Ukraine. American public perception is the major reason why US withdrew from Vietnam after all, in spite of body count that Pentagon touted. This is propaganda war as much as martial.
