Depends on what and how much of the what is being destroyed per shot. Even dumb artillery shells, in the quantities Russian has been firing, are collectively cheap. And much less costly to Ukraine for them to blow up in Russian dump than in their cities. And at least some of what Russia has been firing are somewhat precise missiles. Likely cheaper than our stuff, but how many rounds can you get with one hit. How many secondary explosions can that one hit generate to multiply your results. And if Russia has to move their ammo dumps further back to escape the greater range of our missiles its that much more stress on their weakness, logistics. Very good strategy from Ukrainian viewpoint. Especially when someone else is paying for the shots.
“much more stress on their weakness, logistics.”
Everyday, about 135 million Russian chow down, often with food brought from faraway places such as the country of Georgia.
Russians have tents.
Some may have ammo in them, but many others won’t.
Xi would say waste US munitions on Russian tents rather than on Chinese soldiers reclaiming Taiwan.
Russia has no “precise” missiles like it has no “precise” artillery shells.
If one of either hit its target, (assuming the missile is not in the 60% that fail on launch), it is because they fired enough missiles to blanket the general area.
Russian artillery shells were made in bulk during the Soviet area and cost nothing to use -mostly for the 122mm tubes.
