It has long been said that technology changes warfare. But what changes have taken place in the Russia-Ukraine war?

While relatively new, 21st century-style factors can be observed in this war, such as the use of drones and satellite information as well as cyberattacks, 20th century-style technologies and operations are being used at the same time, including besieging cities with heavy armaments and airborne troops conducting occupation operations.

Needless to say, it is not rare for new and old technologies to be used in a mixed manner in warfare. Such a case was seen even in 1991 in the Gulf War, which triggered debate over a revolution in military affairs.
