As thousands of protesters in Hong Kong gather to protest the proposed “Extradition Bill”, police have used “less lethal” weaponry produced by the company American company Amtec Less Lethal Systems. A tweet posted on June 12th shows a cartridge clearly labelled “ALS – 1202 – Rubber Rocket”. According to the ALS website, the 1202 cartridge is a 12 guage “high velocity rubber finned projectile that is designed to be direct fired, producing blunt trauma and pain compliance.” It has a range of around 120 feet.
AmTec Less Lethal Systems (ALS) produces a wide range of “less lethal” weapons and equipment designed for use by police, law enforcement, security, prison and military personnel in its factory in Florida, USA. War Resisters’ International published a full profile on Amtec Less Lethal Systems in March 2019 – this can be found here: https://www.wri-irg.org/en/story/2019/amtec-less-lethal-systems
RiotID - a civic media project helping people identify, monitor and record the use of riot control against civilians - identified another weapon as an N225 Rubber Bursting CS grenade, produced by the British company Chemring Countermeasures Ltd, part of the Chemring Group. After large amounts of tear gas was used against protesters in Hong Kong in 2014, Chemring confirmed they were a long-term supplier of tear gas. In 2015 the British government granted an open export license, allowing Chemring to supply unlimited amounts of tear gas to Hong Kong for five years.
A media company posted another photo on twitter which showed police armed with shotguns labelled “less lethal”, and could be used to fire a range of different types of ammunition. Some companies (such as Wilson Combat) produce similar looking weapons specifically for firing "less lethal" ammunition, but it is also possible to adapt standard shot guns.
