Zheng-Dao Heavy Industries Mass Driver MD-10 'Trebuchet'

A man-portable electromagnetic mass driver that accelerates a 500-gram steel slug to Mach 3. The Trebuchet is, in essence, a scaled-down naval weapon system — the same magnetic acceleration technology that launches anti-ship projectiles, compressed into a shoulder-fired platform that weighs 25 kg.

Zheng-Dao designed the MD-10 for anti-vehicle and anti-structure operations where conventional anti-materiel rifles lack the kinetic energy to defeat hardened targets. The weapon's 500-gram slug delivers approximately 500 kilojoules of kinetic energy on impact — equivalent to a small explosive charge, but delivered as pure physical force. The slug does not explode; it simply transfers its kinetic energy to the target, producing catastrophic structural failure through impact dynamics.

The Trebuchet's recoil is managed by a magnetic recoil dampening system that distributes the reaction force over 200 milliseconds, reducing felt recoil to manageable levels for a braced operator. Without this system, the weapon's recoil would break the operator's shoulder.

power_source: Dorsal fusion cell, 10 shots per cell

tactical use

The Trebuchet is deployed against targets that shrug off conventional anti-materiel weapons — main battle vehicles, reinforced command bunkers, and armored infrastructure. A single MD-10 slug can disable a medium armored vehicle through kinetic shock alone, and the weapon's pure-kinetic nature means it defeats reactive armor that is designed to counter chemical-energy warheads. Operators describe firing the Trebuchet as 'throwing a building at someone' — the slug's mass and velocity create an impact that nothing survives.

cultural context

The MD-10 occupies a unique niche as a man-portable weapon that delivers vehicle-grade destructive force. In GLMZ's military culture, Trebuchet operators are regarded with a mixture of respect and pity — respect for the devastating capability they bring to a fight, and pity for the physical toll of carrying and operating a 25-kilogram weapon that punishes the body even with magnetic recoil dampening. Veterans of MD-10 operations report chronic shoulder and spinal injuries.

story hooks

A Trebuchet slug was found embedded in the foundation of a building — fired from ground level, it punched through the entire structure and buried itself in the earth beneath. The building is now structurally compromised, and the residents are refusing to evacuate because they have nowhere to go.
A black-market armorer has modified an MD-10 to fire shaped projectiles instead of solid slugs — the modified rounds mushroom on impact, creating a wider damage radius at the cost of penetration. The modification turns a precision anti-vehicle weapon into a terror weapon.

physical description

visual profile	A brutalist electromagnetic rifle with exaggerated proportions — a massive, blocky accelerator chamber dominates the upper receiver, flanked by stabilizing rails and heat-dissipation fins. The silhouette is aggressive and industrial, resembling a scaled-down naval gun mounted on a rifle stock. Heavy, purposeful, intimidating.
dimensions	156 cm overall length, 28 cm width across stabilizer rails, 12 cm depth at chamber. Barrel/accelerator tube: 84 cm. Firing stock extends 38 cm rearward.
weight description	A genuinely heavy weapon — 25 kg base unit feels like shouldering a loaded toolbox. The weight is front-loaded, requiring braced shooting positions. The dorsal fusion cell adds another 8 kg mounted on the undercarriage. Unwieldy without proper stance and support.
primary material	Stamped steel accelerator chamber, reinforced carbon-composite stock and handguard, aluminum alloy mounting rails for modularity. The magnetic coil assembly is shielded in a ferrous-core housing.
finish	Industrial matte black with brushed steel accelerator tube. The coil housing shows oxidized copper patina from heavy electromagnetic cycling. Tactical rail surfaces are anodized gray. Scorched polymer grip wrapping from repeated capacitor discharge heat.
color scheme	Dominant matte black with gunmetal gray accents on the rails. Copper-bronze discoloration visible around coil vents. Fusion cell is industrial orange with black warning striping.
grip texture	Heavily textured, scorched rubberized polymer — designed for sweating, augmented hands. The rear stock features a knurled steel cheek rest. All gripping surfaces are aggressively textured to prevent slipping under recoil.
distinctive features	Oversized cylindrical accelerator chamber with visible copper coil windings through vented steel lattice Two parallel stabilizer rails running the full length, mounted at 45-degree angles for rigid bracing Massive electromagnetic recoil dampening actuator mounted beneath the chamber — a chromed pneumatic-magnetic hybrid cylinder Array of amber and red LED status indicators clustered on the left receiver — power, charge state, thermal warning, capacitor status Heat radiator fins molded into the stock and chamber housing, showing scorch marks from thermal cycling Modular dorsal fusion cell mounted on top via quick-disconnect clamps, itself a compact cylindrical unit with orange warning bands Single massive round loading aperture on the starboard side — large enough to hand-load a 500-gram slug Capacitor discharge vents arranged in a grid pattern along the right side, slightly ablated from arcing Serial and nomenclature plates stamped into the receiver in both Mandarin and English Custom wear patterns on the stock from operator shoulders and sustained contact
manufacturer markings	ZHENG-DAO HEAVY INDUSTRIES stamped in block letters across the top of the chamber housing. Model designation MD-10 engraved below. Small serial plate riveted to the left rail. Warning labels in multiple languages decal-applied on the fusion cell: high-voltage hazard and electromagnetic field warnings.
condition typical	Well-maintained but heavily used — scorch marks around vents, micro-abrading on the grip from gloved handling, slight discoloration on the recoil actuator from multiple thermal cycles. The weapon shows professional maintenance rather than cosmetic care. Battle-worn but functional.

Professional product photography: Zheng-Dao MD-10 Trebuchet mass driver rifle mounted horizontally on a dark matte black surface, angled 35 degrees to showcase the massive accelerator chamber and stabilizer rail architecture. Dramatic side-lighting from the left, casting deep shadows that emphasize the industrial geometry and heat-fin textures. Close detail of the copper-discolored coil housing and amber LED indicators glowing softly. Dorsal fusion cell mounted with orange warning stripes visible. The rubberized, scorched grip texture sharp in focus. Industrial neo-noir aesthetic — clinical, militaristic, pure kinetic brutalism. Shot in studio with metallic accents reflecting hard directional light. Dark teal and warm amber ambient wash. Canon EOS R5 quality, hyperreal material definition. --ar 3:2 --v 6
