A Grenade Harness mounted on Ultramarines Cataphractii Pattern Terminator Armour

A Grenade Harness is a type of rapid-fire Imperial Grenade Launcher that was mounted on some patterns of Space Marine Terminator Armour during the Great Crusade and Horus Heresy eras.

The Grenade Harness could unleash a quick barrage of Frag Grenades to serve as an anti-personnel weapon that softened up the opposition before the Terminators charged into combat.
