War, war never changes.
You've heard this phrase before, right? But to what extent it doesn't change?
These is an old ancient technology of throwing tiny metal pieces or stones using slings. We don't know when did this technique appear but it was spread all around the world. Quite possibly it was used even by Neanderthals.
You can treat them as a pistols from a stone age. And they are literally comparable to a modern pistols by a shooting power, while requiring more skills to use.
And when people started using metal "bullets" for throwing, they were already using them to offend the enemy. Imagine getting your friend killed with a bullet having a penis drawn on it.
And here we are, in 21st century. Did the war change a lot? Well, we have improved bullets that are launched with a "magic powder" and can't have things written on them since it worsens the aerodynamics.
We can still draw swears on drones or missiles (or mines that we also throw at enemies). Or even use drones to throw literal silicone dilldos (I've seen a few videos of that already).
So does the war change a lot?
