In what position is the unit guidon once a preparatory command is given?

When a preparatory command is given, the unit guidon is placed in a raised vertical position. This is significant as it signifies readiness and alertness within the unit. The act of raising the guidon prepares soldiers to receive the command that follows, helping to establish an orderly approach to executing movements. The vertical position is a clear signal to personnel that they should focus on the leader's commands, fostering a sense of unity and discipline within the unit. Other positions, such as horizontal or lowered, do not convey the same readiness and alertness, making the raised vertical position the correct choice in this context.
