The rest of their production is crap, including their weapons.
It is a shame the Russians need to fight with such inferior weapons. If they had good weapons, not just shovels, they would not be losing to Ukraine so badly.
“It is a shame the Russians need to fight with such inferior weapons”
You fight with what you have. Overwhelmingly, what Russia has, is what was left over from the Soviet era. They are burning through it at a hectic pace.
They can produce a lot of artillery shells, but more complex systems being sent to the front are overwhelmingly reconditioned equipment pulled from storage, and they mostly took the best stuff first.
Open Source INTelligence (OSINT) analysts have been tracking the emptying out of the old Soviet storage sites from commercial satellite imagery, and tracking as those models of equipment turn up destroyed or captured on the battlefield.
At these burn rates, they can keep up this operational tempo roughly through 2025, all other things remaining equal. Then the party is over, for Russia as a conventional military power.
Intelligence Services around the world are also counting down the old Soviet arsenals, and preparing for a future where Russian power collapses. Russia’s former client states in Central Asia have already significantly shifted to the Chinese sphere of influence, in just the last two years, as have large segments of Russia’s domestic economy, like its auto industry.
