With a clear plan of attack, tiger cats scattered (9)
I believe the answer is:
strategic
'with a clear plan of attack' is the definition.
I can't tell whether this definition defines the answer.
'tiger cats scattered' is the wordplay.
'scattered' is an anagram indicator.
'tiger'+'cats'='tigercats'
'tigercats' anagrammed gives 'STRATEGIC'.
Can you help me to learn more?
(Other definitions for strategic that I've seen before include "Forming part of a long-term plan" , "Relating to long-term plans" , "To do with a carefully workedout plan of action" , "Tactical" , "Of long-term planning" .)
