Most Russian troops are support, not fighters, and they are stretched too thin

 

 "At the start of the war, Russia had 120 BTGs around Ukraine. Two days ago, the Ukrainian General Staff claimed it had damaged or destroyed 31 Russian BTGs, which seems reasonable, given you only need to kill or incapacitate 60 soldiers or 15 vehicles to force its withdrawal. So while it may be true, as the Pentagon announced today, that Russia still has a little less than 90% of its forces available, that is far less impressive if it has lost a quarter of its initial BTGs. And sure, the remnants will reconstitute, but they will necessarily be of lower quality—troops who have never trained together, with leadership they don’t know or trust, and backfilled with new recruits, foreign fighters, or even greener conscripts.
