The 200k invasion army was supposedly better trained and better equipped and had other advantages like robust air support and still functioning supply lines. What happened to those soldiers? No one cares, let's throw another 300k into it, just with less of everything, and see how that works out. Maybe shift some generals around, yeah, that'll do it.
The question is not for me, but I will answer. Recently, a detachment of special forces from Ukraine returned to my city. They left six months ago and only now have they been given vacation leave (although the planned rotation should be carried out after six weeks of hostilities). Six months instead of six weeks - this is the price of the shortage of manpower involved in the special operation.
