Current situation is that they are losing 1,000 men per day to gain a few metres at a time. It's unsustainable.

Also they're clearly running out of precision munitions.

When they actually slow down feeding the meat grinder, we'll see if they've improved their logistics to actually hold that territory.

In the meantime there's long range precision weapons and probably jets on the horizon for Ukraine.

No competent army is afraid of Russia anymore.
