A belt-fed automatic grenade launcher designed for vehicle mounting or emplaced defensive positions. The MGL-8 fires standard 40mm grenades from a 32-round belt at a cyclic rate of 300 rounds per minute, creating a sustained barrage that can suppress an area the size of a city block. The weapon weighs 28 kg without ammunition and is not designed for individual carry — it is a crew-served weapon intended for checkpoints, vehicle turrets, and fixed defensive positions.

Zheng-Dao manufactures the Thresher for military customers, but the weapon has appeared in GLMZ's inter-corporate conflicts when escalation moves beyond small arms. During the Tier 4 corridor dispute of 2196, both sides deployed vehicle-mounted Threshers in residential areas, and the resulting collateral damage killed more civilians than combatants. The weapon is effective precisely because it is indiscriminate — 300 grenades per minute turns everything in the target area into debris regardless of its tactical significance.
