Earlier quoted context omitted.
IFV are not dead, rocket launchers as well. Even tanks are still a key. At the end people are capturing land/city, not drones. But drones are changing warfare. Drone hunting other drones, drone with self guidance - they are being used in battle right now. 500$ or even less is the cost of FPV drone with night camera capable to carry 2kg bomb. Russia is buying soldiers for up to $25000 to be killed by such cheap drone…
Those drones are getting lost / shot down / missing their targets at high rate. But since they are relatively cheap, they almost effectively artillery shells right now. Don't need a high kill rate when you have lots of them.
And one regular 155mm shell is 5x more expensive than FPV drone.
