Actually, this is the folly of the AFU.
Evidently the Russians have erected massive and deep defense structures in the south. Looks like they are not going anywhere.
Well, they were dug with stolen equipment...not by hand. (Easy stuff to do requiring minimal effort)
It's actually easy to make trenches....it's a LOT harder to fill them.
There's a lot of evidence to suggest that Russia is running short of equipment and qualified manpower.
Commanders are in short supply...so are supplies. Where everyone watches ammunition carefully an army doesn't operate just on bullets alone. In the video you posted earlier the soldier was wearing foot wraps instead of socks....not that Russians don't wear socks...they do. But they are out of socks and now have to rely upon foot wraps. Same problem with NV goggles and scopes. Same with winter clothing and boots. Stealing supplies and selling them on the black market is a foregone conclusion for soldiers. Has been for a long time.
Good leaders are difficult to find in the military to begin with. It's an inherent skill that most don't have. That's why there have been mutiny and lots of soldiers are posted in the rear to shoot deserters.
Ukraine has the upper hand in the coming offensive with better training, high morale and trust in the command structure. Also modern weaponry and supplies donated by the WHOLE WORLD.
You can side with the perpetrator in this conflict or you can side with those who say it is wrong to steal and lie.
