High-volume, low-cost military equipment is redefining modern warfare
In Kyiv, air raid sirens force local residents to seek shelter as soon as possible.
The pace at which they do so is key, as more often than not Russia’s cruise and ballistic missiles can hit Ukraine’s capital with worrying efficacy.
Driving the Kremlin’s attacks are commonly Iskander and Kalibr rockets, which cost $1m (£807,000) apiece and strike their targets within minutes.
However, the weapons that have caused Ukraine greater economic damage of late are drones that cost as little as $10,000.
