The Fourth War(1990)

"Two proud heroes with no one left to fight... But each other."

Overview

Cold War adversaries Col. Jack Knowles and his Russian counterpart, Col. Valachev, are stationed on opposite sides of the German-Czech border. Both men are responsible for a group of troops in their remote settings, and both have been shaped by their combat experiences and a shared aversion to their superiors' ways of doing things. After a defector is killed, things escalate into a full-fledged battle with serious geopolitical ramifications.
