Final answer:
The speaker uses both pathos and ethos to persuade the troops by connecting emotionally and establishing her credibility as a leader who will join them in battle.
Step-by-step explanation:
The rhetorical device being employed in Selection 2 is a combination of pathos and ethos. The speaker is attempting to persuade, motivate, and inspire the troops to battle. This is achieved through an emotional appeal, stirring up feelings of courage and loyalty by presenting herself as the ultimate leader who will take up arms alongside them. Additionally, the speaker establishes credibility and authority by assuming the roles of general, judge, and rewarder, hence appealing to ethos. Such language is strategically used to elicit a strong emotional response while also reinforcing the speaker's character and leadership qualities.
