Crazy.
Drones remind me of the introduction of the Cross-Bow.
At one time the heavily armored mounted knight was the F-35 of his day.
Quality armor was hugely expensive. The knights were those rich enough to afford the mount and armor.
On the battlefield against unarmored infantry they were a feared weapon.
The peasants on the ground beast weapon was a pike. Effective but limited to defense.
Then the introduction of the cross-bow.
Even a dirt poor untrained peasant with a cross-bow could send a bolt right through that shiny high tech armor.
And a cross-bow cost a tiny fraction of a mount and fine armor.
An army of cross-bows could decimate a calvary of armored knights.
