Pinned beneath the rail guns with Bobbie's first wave, Amos spots the reactor vulnerability and holds the assault line while her strike disables the defenses.
Amos Burton joins Bobbie Draper's first Medina assault wave, taking the Roci mechanic's blunt competence and protective violence into a badly improvised landing craft. On Ring Station the force immediately discovers guarded Martian-style bunkers and armed troops, leaving it pinned against the curve of the alien surface instead of cutting into the rail-gun controls.
Amos falls into Bobbie's movement and helps the OPA soldiers keep the defenders occupied behind the walls. Seeing the rail guns fire continuously, he identifies their vulnerability: whatever enormous fusion reactor supplies their power and cooling must lie beneath an emplacement, likely at the gun that is radiating hottest. The observation gives Bobbie a target when ordinary frontal assault has stalled.
While Bobbie flies their landing boat into that reactor, Amos stays with the pinned force and watches the consequences spread across the station. The rail gun powers down, the remaining defenders retreat, and the structural bands begin moving as the blast disrupts the alien station. He cuts off the frightened enemy radio traffic, checks the practical result, and returns to shooting as the mission shifts from taking intact guns to exploiting guns that no one can use.
A heavily built adult man with close-cropped dark hair, a blunt open face, and an amiable but watchful expression; he wears practical vacuum combat gear while fighting on the blue surface of the alien station.
Amos supplies the tactical insight and steady ground fire that let Bobbie turn a pinned assault into an opening for the fleet.
