In the story "In Another Country," why does the narrator see himself as different from the other wounded soldiers in the hospital?

He thinks the others are heroic and he is not.

He thinks he's better than the others.

He sees himself as different because he is an American and does not have the same sense of camaraderie and unity with the other soldiers. He also feels disconnected from their shared experiences and struggles due to his position as an outsider in the foreign country. Additionally, he struggles with reconciling his own feelings of loss and alienation with the bravery and resilience displayed by the other soldiers.
