Remote Guns

A remote gun is a gun that is controlled from a distance. The user of the gun wants to distance themselves from the gun for obvious reasons:

Invincibility. The suspect (or target) will fight the most obvious threat to themselves. In a fight, a suspect will thus shoot at the gun shooting at them. If the gun is operated remotely, then there is no risk to the user. The only person that is going to lose the fight is the suspect. In the unlikely event of a suspect winning a fight, a broken remote gun is much easier to fix than a human life.
Force multiplier. One user can operate many remote guns simultaneously, bringing fire on the suspect from different directions.
Morale. Nothing is more demoralising than fighting a machine.
Environment. Humans are less effective in the cold, rain, snow, night, dust, heat. Remote guns have a wider operating environment than humans.

Remote guns are classified by users:

Military remote guns. Used by Armies, Navies and Air Forces in many countries. Demilitarized zones.
Border control remote guns. Used in high risk areas.
Civilian remote guns. Used by civilians at high risk such as embassies, airports, key infrastructure, farmers, ships and private security.
DIY remote guns (Do It Yourself). Made by enthusiasts and preppers.
