Where are the metaphors in the sniper?

In "The Sniper" by Liam O'Flaherty, metaphors are used to convey the internal and external conflicts of the protagonist. The city is described as a "battleground," representing not only the physical war but also the moral struggles faced by the sniper. The act of shooting the enemy is metaphorically linked to the loss of humanity, illustrating how war dehumanizes individuals. Additionally, the sniper's ultimate realization about his own brother emphasizes the tragic consequences of conflict, serving as a powerful metaphor for the futility of war.
