The chief engineer means that Decoud's plan of Sulaco Separation accords with Charles Gould's character because Gould is already the "King of Sulaco" in popular speech. But on another level, the specific "move" of getting rid of the silver (symbolically, throwing off phony ideology and resorting to brute conquest) accords with Gould's allegorical "character" as material progress, which is now starting to be revealed as a conquering force in human affairs. The "game" of openly acknowledging progress as conquest is one that Holroyd certainly plays.
