What is the author's style in The Sniper by Liam O'Flaherty?

The narrative takes a limited, third-person point of view. The action is entirely funneled through the protagonist. The reader sees only through his eyes, hears sounds through his ears, and processes events through his thoughts. Despite this limited point of view, readers can clearly follow the action. The sniper observes the old woman on the street below as she talks to the soldier in the turret of the armored car.
