Understanding Rearguard: Definition, Role, and Examples

Rearguard is a military term that refers to a unit or force that is positioned at the rear of an army or other military formation, and is typically responsible for providing protection and support to the main forces. The rearguard can be made up of troops who are not directly involved in the frontline fighting, but who are tasked with defending against enemy attacks from behind.

In a broader sense, the term "rearguard" can also be used more generally to describe any group or force that provides support and protection to the main effort, rather than being directly involved in the primary activity or mission. For example, a company might have a rearguard team that is responsible for providing logistical support and security for the rest of the organization.

The word "rearguard" comes from the French phrase "garde arrière," which means "back guard." It has been used in military contexts since at least the 17th century, and is still commonly used today to describe various types of supporting forces.
