Sailors are in a ______ when placed in formation one behind another.

When sailors are arranged in formation one behind another, they are positioned in a structure known as a column. This formation is characterized by individuals being aligned in a vertical stack, where each person is directly behind the one in front. This allows for clear organization and movement, especially in tactical situations.

A column formation is particularly advantageous for advancing through narrow spaces or for maintaining a certain level of unit cohesion and control. It facilitates easier communication and command as leaders can more effectively observe and direct their personnel. This arrangement contrasts with other formations, such as rows or lines, where individuals are aligned side by side. Understanding these distinct formations and their tactical advantages is crucial for effective military operations.
