The Marine Corps wants the device to work at ranges of more than a half mile, beyond the effective range of small arms. Power would be provided by a turbo-alternator and battery system. Researches say they have made technological break through on power supplies to run such weapons even when mounted on vehicles or aircraft.
Any effects are harmless and immediately reversible.
To keep the beam from inflicting burns or damaging eyes, it is limited in power and endurance. The directed-energy ray at the point of exposure causes moisture in the outer layer of the skin to heat to a temporary high enough, that it stings the surrounding tissue like drops of scalding water. Such a weapon would be useful in urban conflicts. It is also valued because they can scramble computer memories and otherwise disable computers that control key battlefield command and communications capabilities. Operational planers say the UAV is the most likely candidate for the HPM weapons since it can get closer to targets without endangering the crews.
