Today's progress was too smooth, solely because of the use of ethyl mercaptan, which trapped at least a thousand members of the Assyrian Group in the underground nuclear bunker, suffocating them like rats inside.

King's Defense had the human advantage, thanks to their heavy firepower and a lot of support from the Russian troops.
But when facing the Black Box hiding underground, the heavy firepower and numerical advantage on the surface were ineffective.
