Twin Rail-Artillery Heavy Walker
Saradook Crimson Sun heavy walker, fielded in sworn pairs. Each arm turret carries two rail barrels from the weapon factories of Mercury, and all four throw a hypervelocity slug every fifth of a second, each with an antimatter charge that bursts across light ground and air units.

01 · Speed
Its thrusters push 3,341 kN, 1.7 times its weight: flat out at sea level it reaches Mach 0.62.
02 · Combat
One frame at base rank, from the battle sheet; ranks strengthen hull, shield and damage.
03 · Weapon
Two arm turrets of two rail barrels each · terminal-effect rounds
Each barrel drives a 63 g slug down its rails at 6 km/s, one barrel after another, across 10 km in under two seconds. Each slug carries 59 ng of antimatter in its own trap, let go as it strikes: a blast that kills in the open out to 4 m and wrecks out to 7 m.
88 an attack every 0.2s (4×): 440 a second. Six attacks land 528 from one frame, 1,056 from the squad of 2.
04 · Available tech
Bought mid-battle with supply, for the squad of 2. Each one gives something and costs something.
Adds a +50% outer targeting band. Attacks, repairs, and boarding channels operate at 55% output beyond native range, and armed squads hold that safer line.
Converts the squad into a breacher: it closes to 45% range and deals +60% damage there, but deals 15% less outside the breach band.
No single hit can strip more than 30% of maximum hull after shields. Mobile units lose 12% thrust; static emplacements lose 18% maximum integrity. Strong into alpha strikes, weak into rapid fire.
Adds 250 shield. If at least 25% charged, a breaking hit loses all hull overflow; the gate re-arms only after recharge reaches 25%.
Burns at +65% speed while marching or closing on its chosen standoff, then disengages in combat; turn authority is halved during the burn.
The Devastator's reactor is opened past its oath. Both guns cycle every 0.12 s for 5 s, then lock for 2 s while it vents: a fifth more fire across the fight, in rushes, and a silence the enemy can count.
Devastator holds a picket around a Guild convoy on its escort gunnery tables: the guns reach 12 km, and leave anything inside 2 km to the clan's close guard.
Devastator feeds penetrator rounds from the weapon factories of Mercury: 150 a bolt against a heavy, assault or titan frame, on a cycle a quarter slower.
Devastator pairs swear one oath and fight as one: both frames of the squad lay their guns on the same mark, and it falls in half the time. Everything else in the sky waits its turn.
Devastator packs a Sunfire charge in every round that shakes what it hits: a struck unit moves 30% slower for 3 s, so a light flyer cannot break off, for 10% less damage.
Devastator jackets each slug in shrapnel that bursts on its mark: full force within 500 m and fading out to 1.5 km, for 15% less on the mark itself.
Devastator wears clan plate on both gun arms, raised as it fires. It takes 800 points of return fire across the forward 72°. Fire from the flank goes past it.
Devastator gunners share the link with a war-priest of the clan. Cloaks within 8 km are stripped, and what is revealed is marked for allied fire at 8% more damage.
