Which formation is designed for rapid deployment to flanks?

• A. Staggered trail left
• B. Diamond
• C. Echelon right
• D. Vee

Answer: (C)

An echelon formation places elements diagonally behind and to the side of the lead, creating a ready-made pathway to the flank. This diagonal layout lets the unit pivot and move laterally as a group, enabling rapid deployment to either flank while maintaining mutual support and fields of fire to the front and to the side. In rapid flank moves, the trailing elements are already offset and can swing into position without re-forming, which is exactly what you want for quick, coordinated repositioning.

The other formations serve different purposes. A diamond offers broad, all-around security and is not optimized for swiftly pulling troops to one side. The Vee concentrates forces forward, which is great for guiding and concentrating fire, but not for quick flank deployment. A staggered trail left emphasizes spacing and concealment in a linear advance, but it hinders fast, coordinated flank shifts.
