Russia has been firing missiles from its S-400 air-defense system on ballistic trajectories against Ukrainian ground targets, including industrial areas. This is a secondary use of an air-defense weapon rather than its main purpose. The missiles are mixed with Iskander and other weapons in larger attacks. The practice helps increase the number of fast threats Ukraine must defend against but offers less precision and power than dedicated strike missiles.
