I have a feeling Russia has changed, to me it looks like they using the current situation as a testbed for both improving tactics & checking if weapon systems perform in combat as well as they did on the range. That's my take on why they are making limited use of high end expensive stuff just to check it performs as expected.
Russia took on board Western thinking of quality over quantity a while back & are mow seeing just how this works & trying to refine it, she is not the same animal she used to be.
