The Ukraine war is going to bring one question to the forefront -- Is the age of tanks and armored vehicles over?
Have hand-held anti-armor weapons coupled with small drones made armor irrelevant on a typical modern battlefield assuming the the troops are well supplied with these weapons. The toll on Russian armor in the Ukraine makes it appear so. In a battlefield that is not completely open and/or flat like a desert - it appears even the most advanced armored vehicles can easily be picked off with hand-held weapons plus drones for spotting. Additionally larger drones can launch anti-armor weapons and suicide drones play a role.
Will the future role of armored vehicles be confined to transport and operation as long range artillery for bombardment -- but not direct engagement with enemy troops.
The results of the Ukraine war has opened this question. Is it that the Russians are simply poorly using their armor in combined troop tactics or has portable battlefield technology made armor irrelevant. Are tanks going the path of battleships in WWII when air power made the battleship irrelevant? Leading the rise of carriers as the central point of a sea task force.
