Massed Ground Combat

The ground battle is fought somewhere specific, and the place is not decoration. It is the second character of the engagement, weighted equal to the enemy. Render it once, in Deployment, and then use it — every later movement obeys it.

• The ground itself. Mud that holds a wheeled vehicle and lets a walker through. Bedrock no entrenching tool will break. Marsh that funnels infantry to a single causeway. A river the enemy must cross at one of three fords. The writer who renders the terrain renders half the battle.
• Gravity and weather. Plate on a high-gravity world burns through its battery in hours instead of days. Rain on the wire turns the trench to slurry by the second night. Cold thickens the lubricants of a heavy frame and slows the rate of fire. Render these once, plainly, and the battle has a body.
• The line as occupation of ground. The ground line is not a chalk-mark on a map. It is positions — a trench, a redoubt, a strongpoint, a fall-back line a kilometre to the rear, a fire-base. The reader who can name the positions can follow the battle.
• The cradle behind the line sits on the same dirt. Show it — the village in the valley, the column of citizens on the rear road, the vault built into the rock the line stands on the slope of. Pro Humanitate on the ground is concrete and visible.

The void battle decides in minutes. The ground battle decides in hours and days. This is the central craft fact of the domain, and the prose must honour it.

• The bombardment. Before the assault wave there is the bombardment — an hour, three hours, a day. The trench shakes and holds; men are killed and replaced; men go mad in the noise. Render the bombardment as a phase, not a beat. Let the reader feel an hour passing inside a position the bombardment will not lift from.
• The waiting. Most of a ground battle is waiting — the hour before the assault, the hour after it is repulsed, the night watch with the wire dark. Waiting is where ground combat lives. A Miles counting magazines, a Decanus reading the field-glass, a medic checking his kit a third time: this is the ground's equivalent of the void's long approach.
• The assault. When it comes it is sudden and over fast — minutes of violence inside the hours of waiting. Render the assault with the prose short of breath; render the hours around it long-breathed.
• The night. Night changes everything — different optics, different sound, different fear. A position held in daylight may be lost at three in the morning, when the cold has bitten through the plate-seals and the wire is full of shadows. The Republic's ground fiction treats night as its own act, not a transition.

• The walker is not the hero. The Centuria is the hero. The walker is the anchor the Centuria forms around. A piece that centres the walker as a one-machine army has departed from combined-arms doctrine.
• The walker dies. A walker on the line is a tall target. Every action that puts one into the Clash should put it at risk. Render the death whole, name the crew once, and let the line feel the anchor go.
• The walker has a pace. It moves at the speed of marching infantry over rough ground, not faster. It does not charge; it advances. A scene that has a walker outrunning the line has lost the doctrine.
• No showcase. The gun is what matters; the cover it provides for the Centuria around it is what matters. Decorative piloting that fetishises the machine is not the register.

Domain safeguards

• The Legio is the actor; combined arms is the form. A piece that resolves a ground battle with infantry alone, or armour alone, or walkers alone, has departed from doctrine.
• No glorification of the assault wave. The line that breaks the wire and charges across open ground is a piece of the battle, never its romantic centre. The Republic does not write the heroic charge as joy; it writes it as the dead the Reckoning will hold.
• Civilians on the battlefield are not staged. Render the citizens being moved to the rear with gravity, not spectacle.
• No mass-casualty arithmetic. The Centuria that started at a hundred ends at thirty-one — and the reader knows three of those names.
• The fighting withdrawal is written as discipline, not defeat. The Republic's hardest ground scenes are not its routs; they are its ordered withdrawals. Render them as the craft they are.
• No enemy caricature, no enemy mystique. Rendered with economy, not derision and not awe. The enemy is what it is.
• The relief is a strategic event. The reserve that arrives at the Turn has marched, or jumped, or driven for hours, and the cost is rendered. A free Turn moves no one.
