Our final entry for the Solar Auxilia (this week, at least…) is the Aethon Heavy Sentinel, a chunky walker that provides heavy close-range firefight support for the brave Lasrifle and Veletaris Sections. With six main weapon options and two missile choices, there’s no nut too tough for this doughty biped to crack –  even the transhuman might of the Legiones Astartes.
