I don’t understand what problem this solves except for snipers Mount this system on a relatively small, silent drone. (There's two more problems to solve, right there, however.) That would be relevant to outdoor recon. This device would not have helped me getting ambushed within 100yards or being the first guy in the door on a raid. Not what "this device" is meant to address.
