eyes right

I'm a little stuck... Click here to teach me more about this clue!

'drill order' is the definition.
'eyes right' can be an answer for 'order' (I've seen this before). I am unsure of the 'drill' bit.

'looks ok' is the wordplay.
'looks' becomes 'eyes' (eyeing is a kind of looking).
'ok' becomes 'right' (I've seen this before).
'eyes'+'right'='EYES RIGHT'

Can you help me to learn more?

(Other definitions for eyes right that I've seen before include "Order" , "Look over there" , "Military command" .)

I've seen this clue in the Sydney Morning Herald.
