Which formation is named after a geometric shape and described as most secure?

• A. Diamond
• B. Trail
• C. Vee
• D. Echelon right

Answer: (A)

In LZ/PZ operations, how a formation positions its elements determines how well threats from all directions can be seen and engaged. The Diamond formation is named for its diamond-shaped layout around a central point, placing team elements at four directions (north, south, east, west) with overlapping fields of fire and mutual support. This gives true 360-degree security: threats approaching from any direction are within someone’s line of sight and weapon coverage, and help can be directed quickly to any side. The arrangement also makes it easier to control entry and exit routes and to respond rapidly to incidents around the landing zone.

In contrast, a Trail keeps forces in a line, which improves speed but leaves flanks vulnerable. A Vee concentrates on an opening or approach corridor, providing strong defense along that axis but leaving other directions less protected. Echelon right staggers units along a diagonal, offering some protection along specific paths but not complete surrounding security.
