The Type 30 Concussion Grenade is designed to kill by creating a powerful localized overpressure through the use of explosives. The grenade is ovoid and has a dark gray exterior with a white stripe around its side. It is used by the Star Army of Yamatai.

It is activated by yanking a loop of string out from the top, which closes an interior electric circuit. These grenades have an estimated lifespan of about 50 years.

Effective Radius: 10 meters.
