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.
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]
So what do you think about a thermobaric bomb, that Russia is using against cities?
"Luckily" unguided
We're using them to slaughter a bunch of baby raping genocidal maniacs, the drones aren't the problem.
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.
