What is this move called?

I watched a movie on Netflix and it was about a woman who is a sniper in the wilderness. I remember a scene at the end a man who is somehow connected with her
starts explaining and apologizes to her about what happened . he shoots his gun by accident. Then the sniper falls off cliff backwards. I remember it being an American film . The sniper never speaks in the entire film. The sniper was wearing a white shirt and she had long black hair.

Battle for Sevastopol?

Lady Death?
