Power Armor is equipment used by special forces in the major government's militaries.
Bobbie Draper's armor is designed to let Marines walk through a nuclear explosion crater minutes after the blast. The HUD, which can be controlled through blinks and eye movements, can show information ranging from maps and combat information to suit diagnostics. It also included a gun built into the right arm. Squad leaders are even able to view their squads life signs and equipment status reports.
