Uniform adopted by active forces to divert one's attention (7)
I believe the answer is:
refocus
'divert one's attention' is the definition.
I can't judge whether this definition defines the answer.
'uniform adopted by active forces' is the wordplay.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'adopted by' means one lot of letters goes inside another (I've seen this in other clues).
'active' indicates anagramming the letters (the letters are active/moving).
'forces' with letters rearranged gives 'refocs'.
'u' inserted within 'refocs' is 'REFOCUS'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for refocus that I've seen before include "Shift one's attention" , "prepare for another shot" , "Adjust lens again" , "As photographer may have to" , "aim again" .)
