History
The Field Marshal first encountered Noble Team while they were investigating the Visegrád Relay. The Field Marshal and attacked Noble Team alongside two of his Zealots, but retreated after shields collapse due to gunfire, while his Zealots were killed by Noble 5 and 6.

It later participated in an attack on the building Noble Team were in. The Field Marshal rode in a Phantom and shot and killed Catherine-B320 with a Needle Rifle. Noble Six grabbed Catherine-B320's pistol and used it to shoot at the Field Marshal with the rest of Noble Team joining in as well. However, the Field Marshal orders the Phantom to fall back, escaping Noble Team again.

The Field Marshal later led a squad of Zealots and Spec Ops Grunts against Noble Six and Emile-A239 while they were trying to get to the UNSC Pillar of Autumn with The Package. The Field Marshal's zealots kill Emile-A239, leaving Noble Six alone to complete his mission. The Field Marshal confronted Noble Six after he killed the remaining Zealots and Spec Ops Grunts. The Field Marshal faced off against the SPARTAN armed with a Fuel Rod Gun and an Energy Sword. After an intense fight, Noble Six killed the Field Marshal.
