A concussive shell

Concussive shells are a type of explosive projectile that can be fired by the Quad K12 grenade launcher, and are a variant of the punisher grenade.[1] On detonation, these shells generate a temporary gravitational warp that disrupts the gravity field surrounding a target or, in certain models, a group of targets.

The warp is not powerful enough to affect anything of massive scale, but Dominion engineers remain optimistic about finding a way to correct this flaw. Concussive shells are a solid, tactical addition to any arsenal,[2] and their effect makes marauders strong tactical support units against infantry surges, in addition to armor.[1]
