If they are produced, and deployed, at scale they would be militarily significant with or without a large size fuel tank surely?

They are intended as anti-personnel weapons and let's say 50 of those are drone dropped along a trench or some other collection of infantry and they could easily take out a lot of people (if not kill at least render militarily useless). A little napalm/white phosphorus goes a long way.

Either way, the endless "robocopping" that these fuckers are getting up to is not reassuring.
