Coalition forces in Afghanistan having been issued a newly-developed heat-ray gun to disperse crowds and repel enemies without injuring them
The Active Denial System (ADS) uses a focused invisible beam, which causes an “intolerable heating sensation" but does not permanently harm the skin.
The first batch of the vehicle-mounted non-lethal weapons has been sent to US troops in the war-torn country but it has not yet been used on the battlefield.
When the beam is pointed at a person, it penetrates the skin to the equivalent of three sheets of paper – enough to cause pain by burning nerve endings.
The discomfort is enough to force people to move away but not to cause long-term damage. The US military says the chance of injury from the system is 0.1 per cent.
