A scalar (electrogravitic) field allows for the manipulation of gravity.
See: Scalar Field
Strong scalar fields create electrical surge comparable to an electromagnetic pulse, but arising everywhere where gravity is effective (almost anywhere but a gravity shielded starship). This electrical surge will kill lifeforms, detonate fuels and explosives, fry electronics, combust combustibles, and vaporize ablative armor.
Less powerful scalar fields can be used as taser-like stun weapons and are used in military pistols such as the Nekovalkyrja Service Pistol, Type 30.
