Design an icon for the mobile game featuring a clear depiction of a soldier facing towards the camera, ensuring the entire body is visible. The soldier should be portrayed as emerging from a battle, with one hand holding a weapon and the other hand raised victoriously. The soldier's face should be partially obscured by shadows to add depth and mystery. Utilize a color palette predominantly composed of white, grey, and black tones to convey the gritty and intense atmosphere of warfare. The background can be kept simple or feature subtle elements of a battlefield to enhance the narrative
