Mentioned in "Avalon, Part 1"
Douglas MacArthur was an United States Army General during World War II. Major General Henry Landry told Major General Jack O'Neill that "A general's only as good as the people he commands." O'Neill asks who said that and Landry says that "he just did but Douglas MacArthur may have said something similar." (SG1: "Avalon, Part 1")
