## I
0.8 seconds since the first railgun impact. The sniper mech's autoloader cycles — chemoacoustic array detects the bolt carrier's mechanical signature at 400 meters altitude, a sharp metallic clack attenuated by distance but unmistakable in its harmonic profile. Second round inbound.
Evasion is not possible. The right leg's drive shaft is intact but cannot generate lateral thrust sufficient to clear the projectile's 40mm kill radius in the 0.22-second flight window. The combat processor selects an alternative: the first round's impact fractured the third thoracic strut, producing a 14cm shard of Old Era titanium still connected to the chassis by a single bolt — angled 31 degrees outward from the chest cavity like a deflection plate that was never designed but now exists.
The body rotates 8 degrees clockwise, aligning the shard with the predicted ballistic trajectory. The round arrives: 40mm tungsten at 1,800 m/s strikes the titanium shard at a 19-degree angle of incidence — below the threshold for penetration, above the threshold for deflection. The penetrator skips, carving a 6cm furrow through the cardiac tissue on the heart's posterior surface, exiting the thoracic cavity 40mm from the organ's central axis. Not a miss. Not a hit. A negotiation with geometry that costs 34 grams of biological heart muscle.
## II
The sniper mech's optical camouflage renders it invisible across the entire electromagnetic spectrum below 100GHz — thermal, visible, near-infrared, all return negative. The aberrant visual system cannot see it. The passive EM scanner cannot detect it. On every sensor channel designed to find a target, the tower's apex reads as empty air.

But the railgun's 40mm projectile travels at 1,800 m/s — Mach 5.3. The sonic shockwave propagates omnidirectionally from the projectile's flight path at 140 decibels, reflecting off the tower's lattice structure, the ground surface, and the terminal housing in a complex acoustic pattern that the chemoacoustic array captures in full. Two shots, two acoustic datasets, two sets of reflections triangulating back to a single origin point.

## III
Kira must be removed from the engagement zone. The terminal housing — 2 meters tall, 1.2 meters wide, 80mm armor plating on all six faces — is the only structure within 120 meters capable of stopping a 40mm penetrator. The housing's rear panel has a maintenance access hatch: 0.6 meters square, large enough.
The right arm — partially functional, bioluminescent muscle fiber supplementing the damaged hydraulic actuator — lifts Kira's 58-kilogram frame and places her inside the housing through the hatch. Her protest registers as elevated vocal output — 74 decibels — but her body does not resist the movement. The hatch closes. She is enclosed in 80mm of armor on all sides. The sniper mech cannot kill her without destroying the terminal, and the terminal is Simon's only means of verifying the Data Spike.
The drive shaft leg plants at the tower's base. Chemoacoustic targeting data feeds to the combat processor: 398 meters vertical, lattice steel structure with guy-wire cables spaced at 120-degree intervals, each cable 32mm braided steel rated for 180-kilonewton loads. Climbable. One leg, one arm, one jaw, one ascent.

Bio-pump output diverts entirely to the right leg. The heart — arrhythmic, hemorrhaging, missing 34 grams of ventricle wall — delivers everything it has left.
