About this creation
From the National Labs comes the DEMPsy. An AIRGV (Artifical Intelligence and Remotely Guided Vehicle) with a powerful battlefield punch, the Directed Electo-Magnetic Pulse system is a tracked mobile weapons platform.
This AIRGV can discharge a powerful EMP erasing software from all but the most heavily shielded electronics, draining batteries and in close proximity frying electrical systems.
