Australian sniper using a periscope rifle at Gallipoli, 1915. He is aided by a spotter with a periscope. The men are believed to belong to the Australian 2nd Light Horse Regiment and the location is probably Quinn's Post.
A few aspects of this photo worth discussing. How uninterested do the men look? they look shattered and most probably have had enough. How on earth can he fire that rifle with any accuracy? a wooden contraption holding it up.
