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.

Approximately a gallon of milk dropped from waist height, but with the impact concentrated into an area 18 mm (~3/4 in) across.
Ah finally and actually useful conversion I can understand.
Its 0.3 hubble-barns of water dropped from 0.0008 sheppys, concentrated into a circle with a 2-can jimmy griffin index diameter.
I dont know how much clearer i can be
So, it sounds like it could probably pierce skin or permanently destroy an eye for example ? Would it be enough to fracture a skull ?

Maybe I’m off but that sounds like a lot of force concentrated into a tiny area. For reference, I know that when I was doing airsoft, a 2mm, 0.2g pellet expelled at 2J could already do some serious damage if it hit the wrong part of the body.
Probably not fracture the skull but like most moving objects you wouldn’t want it heading towards your eye. Decidedly not something you’d want to get hit with, but definitely preferable to the other options.
