In past operations, the effective employment of NLW resolved escalation of force situations,” the document states. “Specifically, the NLW created the right 'direct effect' on the personnel/materiel targeted.

The Raytheon
Active Denial System microwave gun, which heats up the skin of target without (it’s hoped) causing injury, should be upgraded to allow the beam to be used over much longer distances. Ideally the range needs to be such that the device isn’t in potshot distance from small arms fire, although the amount of power required to do this may be prohibitive. The military would also like the units to be smaller and multidirectional.
