In a marching formation, when does the command "Squad Halt" typically occur?

The command "Squad Halt" typically occurs after the completion of the march as it signifies the end of the movement. This command instructs the squad to stop and align themselves at attention, marking a transition from movement to a stationary position. It serves to prepare the squad for further instructions or to finalize a drill.

In this context, the other options do not accurately reflect the timing and purpose of the command. For instance, halting just before turning does not logically align with the intent of continuing forward movement; it would likely create confusion about the expected direction. Similarly, issuing the command before opening ranks does not align with the flow of a drill sequence, as there would be no need to halt before adjusting positions. Finally, calling for a halt during marching exercises would disrupt the rhythm of the drill unnecessarily, as the command’s natural endpoint is intended to follow after the marching is completed.
