Which command directs to remain in a fixed location until further notice?

The command that directs to remain in a fixed location until further notice is "Hold." This command is typically used in various situations, including military operations and air traffic control, to indicate that a unit or aircraft should maintain its current position instead of proceeding to a different location or taking further action.

By using the command "Hold," personnel are instructed to remain stationary and await further instructions, which is crucial for maintaining organization and preventing confusion in dynamic environments. In contrast, the other options do not convey the requirement to remain in a specific location. For example, "Offset" suggests a deviation from a current position, "Buzzer" usually refers to a signaling device rather than a command, and "Strangle" may imply a more aggressive or restrictive action rather than simply holding a position. Therefore, "Hold" is the appropriate command for ensuring that a unit or individual remains fixed in one location.
