A Primaris Astartes Reiver of the Ultramarines outfitted with 2 Shock Grenades on his chest plate

A Shock Grenade is a non-lethal type of Imperial grenade designed to produce a blinding flash of light and loud, raucous noise without causing permanent injury. Shock Grenades are most often used by the Reiver Squads of Primaris Space Marine formations who deploy them to stun the enemy long enough for them to launch a close assault that makes quick work of the foe.
