And lots more of them. A million such drones could depopulate a city better than a neutron bomb.
Even neutron bombs are fairly blunt weapons and will do damage and leave lingering radiation. A massive swarm of drones won’t do as well with people sheltered though for complete depopulation unless they can IR/Radar know where people are and just blow up with a big payload. However, that’ll also do a lot of physical damage.
How many Havoc helicopters would Russia need for a million suicide drones?
If that’s all the made—suicide drones and Havoc helicopters— they’d never make anything else.
The Soviets are gone.
The remaining Russians aren’t ten feet tall. Not much over 5 feet 9 inches, really.
