In story sniper for Liam o Flaherty explain the major conflict

I'm sorry, what do you mean by "deeper conflict"? The Sniper's role of the roof? The Irish Civil War? The setting of The Sniper is integral to the narrative, for it draws its action from the Irish civil war. The story takes place in Dublin, Ireland, in June 1922. At this time, the Irish civil war has been going on for several months. The Republicans hold the Four Courts judicial building, but the Free Staters are attacking them with heavy arms.

The Sniper also takes place between the hours of dusk and dawn. Beginning as "twilight faded into night," the action of the story instantly becomes more dangerous. The sniper must conduct his battle in the dark. He has only "the dim light of the moon that shone through fleecy clouds" to see by. This lack of clarity has a realistic impact in making his task "difficult even in the light of day" even more challenging. The sniper has to aim at his enemy, about fifty yards away, and get off one fatal shot with a revolver. The lack of light also has symbolic significance: it underscores the murky, ambiguous situation that a civil war poses. The civil war pits friends, neighbors, and even family members against one another. As is borne out by the story's ending, people cannot see very clearly during such a conflict.
