Roboute Guilliman through Nimitz, Cunningham and St Vincent

The historical comparison places Roboute Guilliman closer to Eisenhower, Nimitz, Cunningham and St Vincent than to Grant alone. The shared traits are strategic thought, bureaucracy and organization rather than personal combat prowess. Cromwell is another possible parallel because he combined military direction with political and administrative ability. A senior coordinator also needs capable operational subordinates, illustrated by Grant and Sherman or Eisenhower and Patton. The fictional comparison separates theater-level direction from the work of commanders sent to conduct particular campaigns and battles.
