What is true about the echelon formation?

The echelon formation is primarily characterized by its ability to protect an exposed flank, making it advantageous in various combat scenarios. This formation is arranged so that units are positioned at angles to one another, which effectively covers one side and ensures that if an enemy threatens that flank, the units can respond from multiple angles.

By arranging the team or unit in this way, the formation can provide defensive cover while still maintaining the ability to engage in offensive operations. The staggered layout allows for overlapping fields of fire, giving the unit the capacity to defend against attacks from the side that is more vulnerable.

Additionally, this formation can facilitate movement and enable better command and control, as leaders can observe and communicate more effectively with their subordinates across the formation. While not solely designed for offensive actions or concentrating firepower to the rear, the echelon formation indeed excels in protecting flanks and maintaining defensive capabilities.
