What is the primary purpose of the squad echelon formation?

The squad echelon formation is predominantly utilized to protect an exposed flank. This formation allows units to present an asymmetrical shape to the enemy, providing coverage and security to the side that is more vulnerable. By orienting the squad in this way, it consolidates firepower towards the direction of the threat while also fortifying the side that is less secure.

When employing the echelon formation, the squad can efficiently engage an enemy while simultaneously maintaining defensive capabilities against potential attacks from the side or rear. This arrangement is advantageous in situations where the force is transitioning or operating in an area where flank attacks are likely, ensuring that all members are ready to respond effectively to threats from that vulnerable side.

In contrast, other formations and strategies may prioritize aspects such as speed or direct front firepower, but the primary function of the echelon formation is to address and mitigate risks specifically related to exposed flanks. It emphasizes defensive tactics that ensure the squad maintains security against threats that might exploit any weaknesses along the side.
