Interesting, however it is an indicator how badly all Ukrianan artillery could be damaged beyond repair.Damage to Russian artillery during Kherson Counterattack from overuse
While you see Ukrainian supporters laugh at the Russians in that thread, this says to me Russians are pouring a terrifying amount of rounds on AFU in the south. I've also heard rumors that Russian artillery tubes are at times getting hot enough that Russians are lighting up cigarettes by pressing them against the barrel. Wouldn't recommend it though on account of all those recent ammo explosions.
The Russians has way more guns, higher repair capacity, and the guns robust.
Other hand, the M777 example can't overheat this much, because after 30 rounds it needs a repair in Poland.
Means a Soviet gun with 200 rounds untill the barrel is red worth six M777.
So , the Russians has quantitative AND qualitative advantage , the supplied weapons are not usable and the Ukrainans needs six of them to replace one Soviet era gun.
