Remember when the Ukrainian counter offensive failed, in part due to the Russian helicopters coming in and absolutely annihilating the offensive?

I do. The helicopter isn’t dead, neither is the tank.

But their tactics might change, and they might become optionally manned, because why not?

But if you need quick reaction, massive firepower, or troop transport either quickly or in difficult to reach places, good luck doing it with drones or wheeled vehicles.
