Stalker

A man in military gear plays an acoustic guitar in a muddy, rural setting with wooden houses and a truck in the background. The scene transitions to another man eating from a can by a fire, followed by a man with a gas mask and rifle in a war-torn urban area, a man drinking beer in a dimly lit bar, a man in a military uniform in a room with maps and a globe, and finally a man crouching in a field with a rifle and a truck in the distance.
