You know...as the battlefield becomes ever more automated, there might be a very brief window where the winged hussars could make a comeback.
Let's say you have a battlefield riddled with smart drones. They have image recognition and immediately attack anything resembling a tank or other military asset. Do you think anyone bothered to program the drones to seek out and attack a unit outfit like 18th century Polish cavalry? A charge on horseback just might be able to ride completely undisturbed through the right kind of drone-controlled battlefield.
They would be programmed to kill anything that moved just to be sure they get everything. They will be deployed like mine fields except the owners could disable them to move through the drone field.
