Pneumatic cannon
Also known as Pneumatic launcher. Finned projectile reaches 600m. Human Electro-Muscular Incapacitation Rounds HEMI rounds which are being developed by several manufacturers utilize a barbed or sticky nose to attach to the clothing of the targeted individual to deliver a debilitating electric shock. The Eclipse variable velocity system provides safe deployment speeds at any range to compensate for the heavier weight of these rounds.https://eclipsedefense.com/products/#launchers

https://www.youtube.com/watch?v=eKMKtpaq1gE eclipse technologies. Can put out 91joules, which is just under lethal. Comes in three versions, a barrel roll and linear magazine fed system. Punches a hole through a sand blanket. This design can easily be copied. http://www.eclipsedefense.com/products.html. Available ammunition consists of blunt impact rounds with foam tipped or OC powder payloads, pneumatically timed aerosol canisters, smoke, illumination rounds in pyrotechnic or electric versions, IR targeting beacons, hornet's nest and pepperball shot. Any type of material can be used as projectile, making it a lethal weapon or a weapon able to knock over somebody with a bullet proof vest. Under SA law the legality of joule energy used in a paintball marker is actually undefined. This is to prevent an SAPS bribery and intimidation vector, SA isn't Australia, our laws are crafted to prevent abuse.

A "marker" is basically any type of smooth pipe of whatever diameter firing a projectile with compressed gas. The law classifies any type of grooved barrel of .22 caliber and above capable of firing any type of bullet via compressed gas or propellant as a firearm. Grooved pellet guns(below .22) are limited though in the joule energy allowed. A smooth barrel firing say a crossbow arrow fitted over it with compressed gas can be any joule energy. This is sensible legislation as classifying smooth barrels as firearms exceeding a certain joule energy will be used by the SAPS as a pretext to solicit bribes as they inspect industrial plants for exceeding an energy in pneumatic applications. http://www.spudfiles.com/how-to-database/topic23160.html

https://www.youtube.com/watch?v=9Wqx-PTeWUw Stinger spike system According to U.S. Department of Justice statistics, a majority of the largest police and sheriff departments are enacting restrictive pursuit driving policies in order to reduce the injuries and property damage associated with high-speed chases. The STINGER SPIKE SYSTEM® allows law enforcement officers to control those situations by stopping fleeing vehicles effectively, reliably, and safely. The STINGER system employs high strength, hollow steel spikes that penetrate all types of tires -- including self-sealing and run-flats -- and deflate them in a regulated manner. This prevents blowouts, slows the perpetrator's vehicle to a safer rate of speed, and allows him to make a controlled stop. And STINGER spikes are effective on all types of vehicles, including cars, trucks, and buses. https://www.fedsig.com/tire-deflationstinger-spike-system
