What command must the OT in charge give when entering or leaving a building?

The command issued by the officer in charge when entering or leaving a building is critical for maintaining order and discipline within the group. The correct command, "FLIGHT, HALT, COVER" followed by "DISMISSED," serves multiple purposes.

First, "FLIGHT, HALT" directs the group to stop and ensures that everyone is accounted for before proceeding, allowing the officer to quickly assess the situation. Following this with "COVER" instructs personnel to assume a position that prepares them for any potential threats, emphasizing readiness and awareness of their surroundings. Finally, when the group is called "DISMISSED," it clearly indicates that individuals can now proceed to enter or exit the building in an orderly manner.

This complete command structure effectively addresses the safety, discipline, and communication needs of the group, ensuring that all members act in unison and with awareness of their environment as they transition between different locations.
