since humans cant fight on a drone battlefield (we will soon learn) why not use them to end all the wars. self detonating multicopters costs nothing compared to large missiles a person can build 4 hybrid gasplant 1kw drones per hour. some go full electric but you need a powergrid for them to recharge with.
with vacuum bombs it can probably be effective on tanks even.
they go further filled with helium too or hot air from the exhaust
