G2 electroshock grenade (Earth-5875)

The G2 electroshock grenade, informally known as the Sonic Electronic Ball Breaker, is a type of timed detonation sonic grenade used by the UNSC Marine Corps and manufactured by the Armat Battlefield Systems.

Operation
Once a G2 is thrown into the ground, it propels itself to one meter away, delivering an instantaneous electric payload of 1,200,000,000 volts. Although incredibly accurate it is not fatal, for the most part, but its energy is enough to stop the central nervous system of targets.
