Last month it was revealed that modified military aircraft drones will carry out surveillance and will be in place for the 2012 Olympics. The flying robot fleet will range from miniature tactical craft to BAE's new HERTI drone as flown in Afghanistan. Unmanned aircraft can be fitted with LRAD speakers producing intense beams of sound that can be used as a loudhailer or deafen the target with a jarring, discordant noise. Helicopters can use high intensity strobe lighting capabilities to cause dizziness, disorientation and loss of balance. A light based personnel immobilisation device would be too dangerous for a manned aircraft crew, but an unmanned strober could be deployed within a few years. Tasers are now so light that they could be mounted on smaller drones.
