After the Human-Covenant war, the Ordnance Commission, held at the Damascus Testing Facility, approved the long-term aggressive focus on defense-centric armor systems. The Mjolnir Powered Armor/Defender is the most notable result of this research. It was tested at the Ankara Resiliency Chamber in Ankara, Luna.
The Defender armor features the Class-4 DFN chest plate and the XV-3 Modular comm tool.
- The helmet is a redesigned JFO helmet from Halo: Reach.
