In "The Sniper", what are the main characteristics of the (IRA) sniper?
He is calm and patient. The author makes this obvious by the sniper's ability to wait on his opponent and to remain almost motionless for a long period of time.
For most of the short story, the sniper appears to be detached and emotionless, but the ending causes the reader to question how such a collect character would proceed after discovering that he had killed his own brother.
The sniper is also a little bit of an Alpha male in that he seems to have extreme confidence in himself and "knows" that he will have victory over his opponent.
