Which of the following statements is NOT a purpose of a military formation?

A military formation serves several key purposes aimed at ensuring the effectiveness and safety of troops during operations. Maintaining unit cohesion is essential, as a well-formed unit is more likely to operate effectively as a cohesive group under stressful conditions. Establishing a tactical advantage is also a primary goal; formations are designed to maximize the strengths of the unit while minimizing vulnerabilities to adversaries. Additionally, the display of military discipline is significant, as formations reflect the professionalism and readiness of the armed forces to both fellow troops and external observers.

While enforcing the two-arm length interval may be practiced during formations, it is more a method of maintaining order and discipline rather than a primary purpose of military formations as a whole. The interval itself contributes to unit discipline but does not encapsulate the broader strategic and operational goals that military formations are intended to achieve.
