What is a disadvantage of the squad file formation?

The squad file formation is primarily designed for rapid movement and maneuverability in a linear direction. While it facilitates coordination and speed, it presents challenges when engaging with the enemy. The linear arrangement can restrict the squad's ability to effectively respond to threats coming from multiple directions, making it less optimal for situations where enemy contact is imminent. In this formation, there is limited opportunity for tactical adjustments necessary to engage effectively with an adversary, especially in environments requiring flanking maneuvers or quick changes in direction. Therefore, the formation's inherent structure does not support the dynamic needs of combat, making it less effective when facing enemy forces directly.
