Some say that tanks are obsolete in modern battlefield. One example is a recent total destruction of Leopard tanks in Ukraine by Russian Lancet drones. On the other hand, it may be just because Leopards were not prepared for such a kind of weapon, and tank designs will adapt for the use of drones. I hope tanks will survive of course :) What do you think?
SPGs = Self-propelled guns
Big wheeled or tracked artillery guns. Eg French Caesar, German PzH2000, Russian Msta-S, etc
AD is just Air Defence. Million systems for different roles and ranges on the battlefield in Ukraine right now.
