SAS Weapons - Arwen 37 Launcher

The Arwen 37 Launcher is a 5-shot anti-riot weapon developed in the 60s by the British Arms Company, RSAF. Firing 37mm projectiles, such as plastic baton rounds and CS or CN tear gas canisters / penetrators, the Arwen is used by law enforcement agencies around the world. The Special Air Service use the Arwen 37 in the counter-terrorism role. A skilled operator could very quickly fill a target building with tear gas, incapacitating all inside, giving the SAS entry teams a vital advantage.
