The drop bay smelled of burnt lithium grease, ionized oxygen, and the sharp, coppery tang of unwashed marine sweat. It was a smell unique to the deep-belly staging decks of the orbital carrier Goliath, a vessel built less like a warship and more like a floating, heavily armored blacksmith shop.

Chief Suit Technician Aris Thorne sat on a turned-over crate of hydraulic couplings, a pair of brass-tipped calipers held lightly in his grease-stained fingers. Before him hung the Mark-VII Exo-Atmospheric Insertion Suit belonging to Master Sergeant Marcus Vance. The suit was seven hundred pounds of tungsten-carbide plating, reinforced titanium joint housings, and synthetic muscle bundles, supported by an internal scaffold of cold-forged iron. To a Marine, it was a chariot of death. To Thorne, it was a complex cluster of potential leaks, stripped threads, and fluid pressure failures waiting to turn a soldier into a frozen, vacuum-sealed sausage.

Thorne leaned in close, bringing his headlamp down until the white beam illuminated the primary neck collar. He slid the caliper blade across the inner lip of the seal track.

"Three point zero two millimeters," Thorne muttered aloud to nobody in particular. He tapped the gauge on the side of his optical rig. "It’s off by two hundredths of a micron, Jax. Look at this."

Across the workbench, Junior Technician Jax—a skinny kid from the lunar colonies whose coveralls were three sizes too large—poked his head out from under the chest cavity of another suit. His face was smeared with dark blue anti-seize compound.

"Two hundredths, Chief?" Jax squinted, wiping his nose with the back of a bare hand. "That's well within tolerance for a drop harness."

Thorne lowered the calipers and turned a heavy, yellowed glare onto the junior tech. "In an environment with atmosphere, Jax, two hundredths of a micron is nothing. In a sub-zero vacuum at forty thousand meters while dropping at Mach six, two hundredths of a micron is a micro-fissure. The air leaves the suit, the blood in Vance’s lungs boils out through his nose, and the pressure seal freezes open. Then I have to spend three hours scrubbing lung tissue out of the neck ring before the next deployment. You want to scrub lung tissue, Jax?"

Jax swallowed hard, his neck bobbing inside his oversized collar. "No, Chief."

"Then throw that gasket in the scrap heap and pull a fresh viton-fluoropolymer ring from the heated locker. And don't grab the cold ones. Cold viton sets hard. Cold viton splits."

"On it," Jax said, scrambling toward the environmental storage cabinets along the bulkhead.

Thorne turned back to Vance’s suit. He ran his calloused thumb over the dark, matte finish of the shoulder pauldron. The metal was cold to the touch—cold iron, pulled straight from the ship’s raw material stores and milled down in the lower decks. The suit bore the deep gouges and pockmarks of four separate planetary drops. A spray of black primer covered old plasma scoring along the left flank, applied hastily during the last transit through the outer rim.

People who sat in the high command centers three decks up liked to talk about the grand strategy of orbital drop warfare. They spoke in terms of trajectories, atmospheric entry corridors, kinetic impact windows, and troop saturation rates. They viewed the drop marines as arrows in a quiver, launched from the sky to shatter enemy defenses before the infantry transports even cleared high orbit.

Down here in the dark, oily grease-pits of Drop Bay Seven, nobody talked about grand strategy. Down here, war was a matter of gaskets, mechanical tolerances, and pneumatic torque specs. A marine did not survive a drop because he was brave, or because his commander was a tactical genius. A marine survived a drop because a twenty-two-year-old technician with grease under his fingernails spent three hours ensuring that an eight-centimeter synthetic rubber ring didn't crack under forty atmospheres of pressure differential.

A heavy pair of combat boots thudded against the steel grating of the elevated walkway above. Thorne didn't need to look up to know who it was. The rhythmic, slightly uneven clump of the right boot belonged to Master Sergeant Vance. Vance had taken a piece of shrapnel through his right calf during the drop over Kaelen Prime two years ago, back when the Mark-VI suits still had a flaw in the ankle articulation plates. Thorne had fixed the suit design himself with a custom-milled deflector guard, but Vance had kept the limp.

Vance descended the iron steps, clutching an aluminum cup of lukewarm, synthetic coffee. He was a broad-shouldered man with a head shaved down to the scalp and a face that looked like it had been carved out of dry teakwood.

"Tell me my rig is ready, Aris," Vance said, his voice sounding like two bricks grinding together. "The bridge says the fleet is dropping out of warp in thirty minutes, and the captain wants the first wave in the tubes sixty seconds after we enter the orbital slot."

Thorne picked up a small brass pick and carefully began scraping out a speck of dried salt from the inner threads of the suit's umbilical port. "Your rig will be ready when I say it’s ready, Sergeant. Right now, your neck gasket is out of spec, your right elbow actuator is dragging by four milliseconds, and your secondary oxygen check-valve has a grain of sand stuck in the bypass seat."

Vance took a slow sip of his coffee, his dark eyes fixated on the disassembled torso hanging from the gantry overhead. "I dropped onto New Antioch with a sand-grit bypass valve once. Worked fine."

"And you spent four hours in the field breathing through a stuck emergency straw because your main loop choked on recirculated condensation," Thorne replied without looking up. "I remember. I was the one who had to clean the mold out of your intake tube when you got back to the ship."

Vance grunted, leaning his hip against the steel workbench. "It’s going to be dirty down there, Aris. Radar says the landing zone is covered in volcanic ash and freezing rain. Half the planet's atmospheric scrubbers went offline when the separatists knocked out the primary power grid."

"All the more reason your seals need to be liquid-tight," Thorne said. He held his hand out toward Jax without turning his head. "Gasket."

Jax, puffing slightly from his sprint across the deck, slapped a warm, flexible ring of dark grey synthetic rubber into Thorne’s open palm. Thorne examined the ring under his headlamp, twisting it gently to check for micro-tears or manufacturing seam lines. Satisfied, he coated the outer rim with a thin film of translucent vacuum grease. The grease smelled faintly of chemical solvents and paraffin.

With practiced, surgical movements, Thorne aligned the gasket inside the neck collar groove. He used a rounded nylon tool to press the rubber down, inch by inch, ensuring that no air pockets were trapped beneath the seal.

"If a gasket buckles," Thorne said, directing the comment toward Jax, who was leaning over his shoulder to watch, "you get what we call a pinch-bleed. High pressure pushes against the buckle, folds it over, and tears the inner wall. To the marine inside, it sounds like a high-pitched whistle. Three seconds later, the suit loses quarter-pressure. Ten seconds later, the suit is dry."

"What happens after ten seconds?" Jax asked softly.

Vance chuckled dryly, taking another swig of coffee. "After ten seconds, kid, you don't have to worry about breathing anymore. The cold takes care of the panic."

"Ignore him," Thorne told the young tech. "After ten seconds, you trigger the emergency foam injector, which fills your chest cavity with quick-setting fire-retardant sealant. You survive, but you spend the next three days spitting up sticky white goo that tastes like liquefied copper."

Thorne picked up the heavy torque wrench laying on the lower shelf of his tool cart. The wrench was an ancient pneumatic model, heavy and clad in black vulcanized rubber, its steel drive lug worn shiny from decades of use. Digital torque wrenches were available all over the ship, but Thorne didn't trust them. Digital sensors could be bluffed by a speck of dust or an inductive charge from a suit's power cell. A mechanical torque wrench, calibrated with iron springs and physical lock-pins, didn't lie.

He fitted the socket onto the high-pressure locking bolt at the rear of Vance’s chest plate.

Clack. Clack. Clack.

Thorne pulled until the wrench gave a sharp, metallic click.

"Forty-five foot-pounds," Thorne announced. "Not forty-four, not forty-six. Forty-five."

"You're a poet, Chief," Vance said, setting his empty coffee cup down on a tray of dirty copper washers. "A real artist."

"I'm the only thing standing between you and an early grave," Thorne snapped, though there was no real heat in his voice. "Get your under-suit on. The drop bay status lights are going to turn yellow any minute, and I don't want your squad standing around in their underwear while the deck officers scream at me over the comms."

Vance straightened up, rolling his bad shoulder. The joke faded from his face, replaced by the flat, cold expression that all orbital drop marines adopted right before a combat plunge. He looked at the long row of twenty suits suspended from the overhead rail system. Each suit was a dark, silent silhouette, suspended by iron chains and umbilical cables that dripped synthetic hydraulic fluid onto the deck plates below.

"How are the rest of the rigs?" Vance asked quietly.

"Sorenson's rig needed a new leg servo," Thorne said, gesturing with his wrench toward a unit three stalls down. "She hit the ramp hard on the last training drop. Crushed the secondary housing. I had to heat the frame with a blowtorch and bend it back into alignment on the anvil. It's solid now, but it's going to creak when she kneels."

"Sorenson can deal with a creak," Vance said. "What about the new kids? Miller and Chen?"

Thorne paused, resting his forearm on the cold iron shoulder plate of Vance's suit. He turned to look at Jax, who was currently struggling to untangle a high-pressure air hose near the wall.

"Their suits are factory fresh," Thorne said, lowering his voice so the junior tech wouldn't hear. "Straight out of the logistics crates from the orbital yards at Terra. Beautiful metal. Flawless paint. Perfectly machined joints."

"You sound like you hate them," Vance observed.

"I do," Thorne grunted. "Factory fresh means they haven't been stressed yet. They haven't been subjected to four hundred degrees of atmospheric friction followed by a hard stop on concrete. I don't trust a piece of iron until it's been cooked twice and beaten with a hammer. New suits have hidden flaws. Micro-voids in the casting. Tolerances that look good on paper but bind up when the metal contracts in the deep cold."

"They'll have to prove themselves today," Vance said.

"The suits or the kids?"

"Both," Vance said.

A low, vibrating hum began to resonate through the deck plates beneath their feet. It was a deep, sub-audible thrum that started in the ship's fusion reactors three hundred meters aft and traveled through the structural spine of the Goliath. A second later, the overhead luminescent tubes flickered, shifting from their harsh, working-day white to a dull, amber yellow.

Overhead, the ship's automated PA system chimed—three sharp, brassy notes that cut through the hiss of steam pipes and the clatter of dropped wrenches.

"All hands, prepare for drop-space translation. Transition to target orbit in fifteen minutes. Drop Bay Seven, prepare suits for preliminary pressurization. All drop personnel report to staging stations."

The bay instantly erupted into organized chaos. Dozens of suit techs in grease-stained coveralls surged out of the maintenance alcoves, pulling pneumatic hoses, ratcheting frame locks, and hauling heavy battery packs on electric carts. The quiet mechanical solitude of Thorne's workstation disappeared, swallowed by the roar of air compressors and the clatter of iron tools.

Jax froze, looking around at the sudden flurry of activity with wide eyes. "Chief? Was that the fifteen-minute warning?"

Thorne didn't panic. He never panicked. Panicking caused a man to drop a washer, or cross-thread an aluminum bolt, or leave an oily thumbprint on an optical sensor glass.

"Calm down, Jax," Thorne said, his voice flat and steady. He tapped the side of the torque wrench against the workbench. "The ship is dropping out of warp in fifteen minutes. That means we have twenty minutes before the marines enter the bays, and another twelve minutes after they dock into their rigs before the drop tubes cycle."

He looked at Vance, who was already stripping off his heavy grey utility tunic to reveal the thick, padded under-suit beneath.

"Twelve minutes to seal," Thorne said, leaning over the suit to attach the primary oxygen line. "Twelve minutes to make sure forty thousand pounds of iron and rubber keep twenty men alive in the dark."

The central telemetry board mounted high above Drop Bay Seven flashed from steady amber to a pulsing crimson. Beneath the bright digital digits, a high-frequency klaxon chimed twice, its tone reverberating through the heavy steel bulkheads. The red LED display cleared its diagnostic diagnostic codes and locked onto a simple, brutal countdown: 29:59... 29:58... 29:57...

That was thirty minutes until orbital detachment. But for Chief Suit Technician Aris Thorne, thirty minutes was a fantasy designed to keep the ship’s bridge staff feeling relaxed. The real number was twelve. Once the drop tubes sealed and the automated safety locks engaged at T-minus twelve minutes, no technician was permitted on the staging gantries. Anything that wasn't torqued, bled, tested, and sealed by the twelve-minute mark went down to the surface as it was—or got left behind in the bay to face a court-martial for equipment failure.

"Clock's running, Jax!" Thorne roared over the rising whine of the primary air scrubbers. "Get the hydraulic test bench online! I want thirty megapascals on the supply lines before the marines set foot on the deck!"

"Bench is spinning up, Chief!" Jax yelled back, wrestling a thick black hose wrapped in braided stainless steel toward the test rig. "Pressure's at eighteen and climbing!"

Thorne wiped his hands on a greasy rag and stepped onto the iron catwalk that snaked along the gantry frame. Suspended from heavy overhead I-beams were twenty Mark-VII insertion suits, hanging like skinned iron giants in a row. Electrician's lamps swung from overhead cables, throwing long, jittery shadows across the matte-black carbide plating. Down the line, six other suit technicians were already bent over their assigned rigs, their pneumatic ratchets whining like angry hornets.

"Thorne!" a sharp, clipped voice barked from the access walkway.

Thorne didn't need to look down to know who it was. Lieutenant Commander Rebecca Vance—no relation to the Master Sergeant, though she possessed an equally alarming lack of patience—was standing at the foot of the gantry stairs. She wore the crisp gray service uniform of the ship's flight deck operations, entirely free of the grease, hydraulic soot, and copper filings that coated every surface in Drop Bay Seven.

"Lieutenant," Thorne said, leaning over the handrail without pausing his inspection of Vance's chest-plate hinge pins.

"Bridge reports we're dropping out of transit behind the planet's shadow," she said, her voice easily cutting through the clatter of the deck. "The primary drop vector is locked. Command wants First Squad in the tubes at T-minus ten. That gives you eighteen minutes to certify all twenty rigs."

Thorne stopped pulling his thread gauge through a set-bolt and looked down at her. "Command can want whatever it likes, Lieutenant. Iron contracts at different rates than carbon-composite under rapid chill. If I rush the pre-chill bleed on those power cores, the cooling jackets will shatter the moment the atmospheric drop hits six hundred degrees."

"You have eighteen minutes, Chief," Rebecca Vance repeated, holding his gaze with cold, unyielding precision. "The drop window over the target sector is tight. If we miss the orbital slot, the planetary defense grid will rotate into coverage, and the landing zone will be smothered in surface-to-orbit plasma fire. I don't care how tight your bolts are if the transport ship gets vaporized in high orbit."

"If the suits fail, they get vaporized on the way down anyway," Thorne grunted, turning back to his work. "I'll have them certified when they're safe. Not a second before."

"Eighteen minutes, Thorne," she said, turning on her heel and marching back toward the armored blast doors that led to the flight deck bridge.

Thorne spat onto the deck plate, watched the drop of saliva sizzle faintly against a warm hydraulic line, and went back to his calipers.

"Jax!" he called out.

"Yeah, Chief?"

"Bring the telemetry slate for suit zero-four. That's Private Chen's rig. I want to see the cold-start diagnostics on his primary life-support bus."

Jax hurried up the catwalk stairs, carrying a scuffed, rubber-armored digital slate in one hand and a bottle of thread-locking fluid in the other. He handed the slate to Thorne, his eyes darting toward the glowing red Descent Clock on the far wall.

26:14... 26:13... 26:12...

"Chen's suit is reading a three percent voltage bleed on the secondary auxiliary loop," Jax said, pointing a grease-stained finger at a scrolling column of green text on the screen. "I checked the pin connections on the lower back harness. They look clean, but the computer keeps flagging a micro-ohm resistance jump every time the gyro-stabilizers spin up."
