A Starship's Mage character as an Allied wartime leader

Where would the Starship's Mage character fit in a non-legislative Allied leadership position during the Second World War?

A land-command role, possibly replacing MacArthur or Patton, is favoured because the character is a principled fixer who finds capable people to carry out the work.

The fictional substitution is judged through the character's leadership style. Dan sees little need to replace most Allied naval commanders, although Gensoul and Darlan receive a less favourable judgment. Replacing MacArthur or Patton is suggested as a more interesting possibility. The character is a principled fixer who identifies capable people and puts them to work. That favours a post requiring delegation and personnel judgment over selection for exceptional personal ability as an admiral. A land-forces command is the preferred outcome. The character's name remains unclear in the captions.
