Although modern technology, including drones and electronic warfare, has shaped the Russia-Ukraine war, the outcome will likely depend on which side can sustain its artillery usage.
Both countries rely heavily on Soviet doctrine that emphasizes artillery, with Russia firing around 10,000 rounds daily and Ukraine about 2,000. Initially, Ukraine relied on its Soviet-era stockpiles of 152mm artillery and ammunition, supplemented by NATO-provided 155mm systems and shells.
Moving forward, Ukraine is in an increasingly stronger position, now having the capability to produce both 155mm howitzers and the corresponding artillery shells.
Indeed, PreRun said similar in his most recent video about Ukraine’s War Economy. Still, percentages or some indication of how close they are to being capable would make me feel less frustrated with the situation.
