What was Eisenhower's role before becoming president?

Eisenhower served as a General in the Army before he became president, playing a crucial role in World War II. His leadership as the Supreme Commander of the Allied Expeditionary Forces in Europe demonstrated his ability to coordinate complex military operations and gain support from various Allied nations. This experience not only established him as a prominent military figure but also shaped his leadership style, emphasizing team collaboration and strategic planning. His military background was a significant asset during his presidency, influencing both domestic and foreign policies as he navigated the Cold War's challenges.

In contrast, the other options represent positions he did not hold: he was never Secretary of State, never commanded the Navy, and was not Chief Justice of the Supreme Court. These roles are significant in their own rights, but they do not relate to Eisenhower's career prior to his presidency.
