Four individuals in military-style camouflage uniforms and helmets, some wearing gas masks, move in formation while holding rifles, advancing from left to right along the side of a light-colored building with a corrugated metal roof, passing a yellow sign with Russian text that reads "Учебное место Выполнение 1 УУС из ПМ" (Training area, Execution of 1 UUS from PM), under bright daylight.
