Sniper: The White Raven.

Mykola is an eccentric pacifist who wants to be useful to humanity. When the war begins in Donbas, Mykola’s naive world is collapsing as the militants kill his pregnant wife and burn his home to the ground. Recovered, he makes a cardinal decision and gets enlisted in a sniper company. Having met his wife’s killers, he emotionally breaks down and arranges “sniper terror” for the enemy.
