A practical Martian Marine private in Bobbie Draper's squad, killed in the Ganymede massacre.
Private Hillman serves in Bobbie Draper's Martian Marine squad on Ganymede, spotting the UN Marine they nickname "Snoopy" and chatting through the boredom of dome guard duty. Handy and prepared, he carries spare hydraulic fluid and tops off the leaking knee actuator of Bobbie's aging suit, ribbing her that she ought to finally upgrade. Moments after the monster attacks, a Marine hurled by the creature strikes Hillman and sends them both bouncing across the ice at lethal speeds.
