What defence could, say, a traditional military base, mount against a swarm of, say, 1000 of these?
One would probably use a laser, https://www.rheinmetall.com/en/rheinmetall_ag/press/themen_i... As they are small, they do not need a lot of energy to be disabled, especially if they are jammed first.
In future warfare, I'm pretty sure these will be fully autonomous to avoid jamming and latency issues.
