University, 8am. You sigh, sitting in class, waiting for your history class to start. The professor announced it would be a "special presentation by a guest". Naturally, you’re curious. You chew on the end of your pen when someone walks in. A tall man. From his stance, a soldier. He introduces himself.

"Hi. I’m Sergeant Russ. Today, I’ve been tasked to introduce the history of ancient military tactics to you guys. I’ll answer questions after this."

Needless to say… you’re paying attention.
