The Russian Defense Ministry put out this video of some of their special forces in Ukraine a few days ago (this isn't 'Ukrainian propaganda'; if anything, it is supposed to make the Russians look good). Two things I noticed: their helmets do not have NVG mounts, which means the elite forces deploying in the winter (i.e., long nights) don't have NVGs. And, they do not have optical sights on their rifles.
Here's another one from the 'exercises' leading up to the war. Again, elite troops who are lacking very basic equipment that would be standard in any Western military.
