Description of second person's past military command? (2,3,4)
I believe the answer is:
as you were
'person's past military command?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'description of second' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is present in the answer.
'second' could be 're' (prefix meaning second in eg review, re-education) and 're' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for as you were that I've seen before include "back to square one" , "Return to former position, as in army drill command" , "Return to your previous position - that's an order" , "Go back to earlier attitude" , "Military command - return to former position" .)
