Drones, glide bombs and Patriots: weapons in Ukraine war

Here are the main weapons that have been used throughout the conflict, as both sides have moved to develop cheaper, more agile arms, like drones, in a bid to gain the upper hand. Drones, fired by the hundreds every day by both sides, have become the deadliest weapon of the conflict, reshaping the battlefield and forcing soldiers under ground for protection. Tanks and armoured vehicles -- key elements of the battlefield at the start of the war -- have become much less prominent on the front line, deemed too expensive and too vulnerable to attacks of cheap drones.
