Easy, commander

A man in a red shirt and black aviator hat holds a long, dark object to his eye like a telescope, his mouth open in a shout or exclamation, then closes it and looks forward with a slight smile; the scene cuts to a different man in a dark jacket and striped shirt, who looks up and to the side with a surprised expression, then the first man reappears, still holding the object to his eye and looking forward. The setting is a dimly lit, enclosed space with metallic structures and warm lighting.
