Snake from Metal Gear Solid

A man dressed in camouflage attire, with a green headband and a black turtleneck underneath his jacket. He is positioned in front of a beige wall, leaning against it with one hand in his pocket and the other holding a gun holster on his hip. The background of the image is out of focus, but it appears to be a room with various objects and decorations. The overall atmosphere suggests that the man is preparing for or participating in some kind of military training exercise or simulation.
