In short: When an army is forced to retreat under heavy enemy pressure, it becomes dangerously vulnerable. This video explores how rearguard units function to protect the main body during an evacuation.

A rearguard is a specific type of unit, typically composed of infantry, tasked with managing a tactical withdrawal. During operations where a military formation must evacuate or retreat—often while under intense pressure from enemy forces—the main body of the army is often unable to fight back and is at high risk of being destroyed. The rearguard serves as a critical buffer to protect this vulnerable retreating force.
