Loitering suicide drones is some dark dark future shit. Im glad drones dont have guns yet. Disgusting world where we'd have such mechanized air orne slaughter.
We're using them to slaughter a bunch of baby raping genocidal maniacs, the drones aren't the problem.
So what do you think about a thermobaric bomb, that Russia is using against cities?
"Luckily" unguided
You don't need a gun when you can create a shotgun like effect covering 15-20m.
E.g. a Russian loitering drone has 2kg of steel ball bearings and plastic explosives combined together. [1]
the US should announce already they are at war against Russia, why are they shy?
Because they aren't. A direct war between the US and Russia would rapidly escalate to nuclear, which is a kind of war that can't be won because of mutual destruction.
They could fight each other indirectly in Ukraine, but I wouldn't expect any direct confrontation by their regular armies.
