What interpersonal skill does TSgt Hammond demonstrate by listening and valuing his subordinates' viewpoints?

The correct choice highlights that listening and valuing subordinates' viewpoints are fundamental aspects of basic interpersonal communication skills. These skills encompass the ability to effectively engage in dialogue, which includes active listening, empathy, and clearly responding to others' thoughts and feelings. By demonstrating these abilities, TSgt Hammond fosters an environment where team members feel heard and respected, which is crucial for building trust and cooperation within a team.

Emotional intelligence is related but more specifically involves recognizing one's own emotions and the emotions of others and using this awareness to guide interactions.
