Of operations, precise as military ones (8)
I believe the answer is:
surgical
I believe this is a double definition.
'of operations' is the first definition.
(I've seen this before)
'precise as military ones' is the second definition.
(as in a surgical bombing)
(Other definitions for surgical that I've seen before include "(Of action) precise, incisive" , "Ugli scar? (anag)" , "Curative" , "Relating to operative procedures" , "(Ward) related to operations" .)
