Which formation is used to protect an exposed flank, particularly when the enemy is known to be on that side?

• A. Squad Line
• B. Squad Echelon Right (Left)
• C. Squad Wedge
• D. Squad Vee

Answer: (B)

Placing the squad in an echelon to the side of the exposed flank maximizes protection where the enemy is known to be. In this setup, the lead element sits toward the flank and a step back from the main line, with the rest of the squad arranged diagonally behind. That diagonal arrangement creates overlapping fields of fire along the flank and gives the unit a clear line of sight and fire toward the suspected enemy approach, while still keeping the squad maneuverable. The echelon offers immediate defensive utility: if the enemy presses that flank, the offside elements can quickly shift fire and maintain mutual support, preventing the flank from being outflanked. It also preserves command and control by keeping most of the squad together in a way that still allows the force to pivot and respond as the situation evolves. Other formations don’t protect a known flank as effectively. A straight line frontally exposes the flank to envelopment; a wedge or Vee prioritizes forward movement and general coverage but doesn’t concentrate or maximize protection on a known enemy side.
