The MILES training system “god gun”.

From Bryan Jones’s blog …

A rifle or sidearm for instance could not disable a tank while conversely heavier weapon systems can do more damage or cause injury to greater numbers of individuals. However, the most powerful weapon in the NTC is a small blue sidearm called the “god gun”. This electronic weapon instantaneously “kills” personnel or vehicles and removes them from the fight when participants are within the kill zone or blast radius of virtual explosions delivered from both grenades and IEDs.

Bryan took this photo when he visited Medina Wasl, the fake Iraqi village at Fort Irwin’s National Training Center. His blog post about the visit is definitely worth reading.
