What are the 3 structural elements in the sniper?

In "The Sniper" by Liam O'Flaherty, the three structural elements include exposition, which introduces the setting and the protagonist, a sniper in a war-torn city; rising action, where tension builds as the sniper engages in a deadly cat-and-mouse game with an enemy; and climax, culminating in the sniper's shocking realization about the identity of his opponent. These elements work together to create a gripping narrative that explores themes of conflict and the harsh realities of war.
