Which sequence represents the correct challenging procedure on sentry duty?

• A. Halt! What goes there?; Advance one and be recognised; Halt; Challenge (password); Advance one and be recognised
• B. Halt; Advance one; Be recognised; Halt; Challenge (password)
• C. Advance one; Halt; Halt; Challenge (password); Be recognised
• D. Halt! What goes there?; Halt; Advance one and be recognised; Challenge (password)

Answer: (A)

The sequence tests getting a visitor through the guard with proper verification in the right order. You begin by stopping the entrant with a clear halt and challenge. Then you require the visitor to advance one pace to be recognised, bringing them into proper range for identification. After that, you halt again to set the position for the password check, perform the password challenge, and only if the password is correct do you allow the visitor to advance one more pace to be recognised and proceed. This order ensures the visitor is visually identified and authorized before entry, keeping the post secure by confirming credentials before granting passage.
