雪地近身格斗（女特工）

Subject: a short-haired female agent in tactical winter gear and a mercenary in dark armor. Action: the mercenary throws a punch; she dodges swiftly and counters with a powerful elbow strike to his face mask, followed by a heavy knee to the stomach; impact shows visible shockwave ripples, sweat and saliva flying as his body folds from the blow. Scene: a snowy military base perimeter at dawn. Light: cold blue-white ambient with hard backlight, vapor breath catching the light. Camera: dynamic handheld tracking the contact moments, shallow shake on impact. Style: gritty photoreal action thriller, high contrast. Audio: heavy breathing, impact thuds, snow crunch, no music. Constraints: maintain both faces, no watermark, no text overlays, no extra limbs, no twins.
