In the Russian-Ukrainian war, there was a change in the weight of the use of some weapons in military actions. The very intensive use of ground artillery is observed. It is estimated that about 70% of Ukrainian military casualties are caused by Russian artillery fire, which is an extraordinary component of the armed forces. The Institute of Strategic Studies (IRUSI) in London notes the accuracy, but especially the short reaction time (up to three minutes) of this weapon. For the Ukrainians, the JAVELIN anti-tank missile and the highly accurate HIMARS systems (error of only 10m from the target) were very effective in hitting some infrastructure elements and warehouses of ammunition and logistical materials. As a result, the Russians had to move some of their warehouses deeper. A significant share is the drones used intensively by both sides, mainly the BAYRAKTAR (Turkish origin) by the Ukrainians and the SHAHED (Iranian origin) by the Russians.
