It always intrigues me to look through good optics at an enemy hundreds of metres away. Beforehand, you could only see him as a small and indistinct shape, then suddenly you can see the details of his uniform, and whether he is short or tall, skinny or fat. You can tell whether or not he has shaved that morning. You know if he is young or old, and if he in an officer or a soldier. You can see the expression on his face, and sometimes your target will be talking to another soldier, or even singing to himself.
