This less lethal launcher from UMX, a sub brand of the German company Umarex, has a built in range finder tied to a laser rangefinder that regulates an electronically controlled valve to ensure a projectile is launched pneumatically to hit a target at no greater than 30 joules of impact force.
This ensures that sufficient force is applied to receive the desired effect while mitigating the risk of causing unnecessary damage.
It is designed to fire a variety of capsules including one containing a pepper spray like powder and one that has an ultraviolet markings dye.

They asked “how much is 30 Joules” and you went “it’s nonsense!” despite the fact that it absolutely isn’t nonsense, and is an actual SI unit.
Way to go insulting people when they call you out. I’m sure you are a very pleasant person to be around. I won’t be responding to your subsequent comments because of your behavior.
