Admiral Greyfield (Sigismundo in the European version of the game) is a CO and leader of the New Rubinelle Army.

Greyfield is first mentioned by Waylon after clearing level seven. He then appears as an ally during the campaign against Lazuria.

After the war with Lazuria is over, he orders Waylon to kill Forsythe, much to Brenner's dismay. Brenner, defiant, orders the troops to leave the area because it was revealed that Greyfield has gone mad, was the true instigator, and was shown to have a superiority complex. Greyfield fires weapons against the hiding spot after he frees the Lazurian prisoners.

With the knowledge of the Creeper being out in the public, some of Greyfield's troops abandoned Greyfield. Support from Greyfield started diminishing as he has lost control of his troops. He is then shown to have little consideration for his troops as anyone who disobeys are considered weak and traitorous.

After a campaign against him, he has failed to launch the Caulder Missiles on time. He is shot by Lin, ending his hunger for power. Greyfield (when alive) referred to himself as King Greyfield the Mighty.


His CO zone boosts all naval units, seaplanes and copters by +10 attack and +40 defence.

As his rank implies, he excels with naval units. He boosts their attack somewhat, but boosts their defense even more. His power resupplies all of his units, giving them fuel, ammo, and building materials.

Greyfield's COP is the only means of restoring material to Rigs and Carriers in the game.


In order to unlock Greyfield as a playable commander, the player must complete Mission 21: "Lin's Gambit".


  • Greyfield is the only commander in Days of Ruin to hold a Naval Rank (Admiral).

  • Greyfield's eyes do have pupils they are just very very small and only really visible in the CO section of the Days of Ruin Strategy Guide.
