Notice how the speaker repeats the word "someone" throughout the poem. What statement about the war is she making by using an indefinite pronoun rather than referring to a specific person?

The speaker's use of an indefinite pronoun reflects her view of the war. By not referring to a specific person, it implies that the main character could not identify the person, that it could have been anyone. The speaker may feel how dehumanizing or senseless war can be.
