Final answer:
A commander's character complexities can be revealed through their choices, actions, and speech, which can have an impact on their legacy.
Step-by-step explanation:
The complexities of a commander's character can be revealed through their choices, actions, and speech. For example, President Kennedy's advisors in the ExComm showed how they balanced their own preferences with an understanding of the president's worldview. Some members of the ExComm tried to persuade the president to take a more aggressive response, while others played to his desire to avoid long-term engagement or escalation. These complexities in the commander's character can shape their decision-making and ultimately impact their legacy.
