The ADS weapon's beam causes pain within 2 to 3 seconds and it becomes intolerable after less than 5 seconds. People's reflex responses to the pain is expected to force them to move out of the beam before their skin can be burnt.

During the experiments, people playing rioters put up their hands when hit and were given a 15-second cooling-down period before being targeted again.
One person suffered a burn in a previous test when the beam was accidentally used on the wrong power setting.
?What happens if someone is unable to move away from the beam??
A vehicle-mounted version of ADS called Sheriff could be in service in Iraq in 2006 according to the Department of Defense, and it is also being evaluated by the US Department of Energy for use in defending nuclear facilities. The US marines and police are both working on portable versions, and the US air force is building a system for controlling riots.
