Not exactly breaking news. Its been coming already for awhile. Russia is officially adopting the wheeled SPH, Following the likes of the French CAESAR and the Chinese PCL-181.
This shows that the European and Chinese mass-adoption of the wheeled SPH is well justified. For Russia to accelerate the adoption of the Malva, even with the Koalitsiya-SV already in production during the Ukraine War. Its a strong sign of approval for the wheeled SPH on the modern battlefield. Wheeled SPHs are much cheaper to produce and maintain than tracked systems. They are also an upgrade over towed artillery pieces. Hence, a very practical system for the modern battlefield.
Its supposed to be a no-brainer. But a number of major militaries have not adopted them yet. The US military being the most obvious one. Even the Russians preferred their traditional tracked systems up until recently.
