Which formation is typically used when the likelihood of enemy contact changes from "remote" to "possible"?

The tactical column formation is designed for movement and provides good control and speed. When the likelihood of enemy contact transitions from "remote" to "possible," this formation allows the squad to maintain a compact structure while still being prepared to respond to threats. The formation's alignment enables elements within the squad to react quickly to situations, either by transitioning into defensive postures or moving to engage as needed.

The tactical column also allows for easy communication and maneuverability, essential when preparing for potential enemy engagement. As formations like the Vee, skirmish line, and wedge are more specialized, they may not provide the same balance of defense and speed, making the tactical column the optimal choice in this scenario where readiness and adaptability are crucial.
