Brother officers from unit, the type synonymous with spears - a concern for those managing the plot (8)
I believe the answer is:
broccoli
'the type synonymous with spears a concern for those managing the plot' is the definition.
I can't judge whether this defines the answer.
'brother officers from unit' is the wordplay.
I cannot quite understand how this works, but
'brother' could be 'bro' and 'bro' is located in the answer.
'unit' could be 'cc' (cc is a kind of unit) and 'cc' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for broccoli that I've seen before include "Cubby --------, co-founder of the James Bond film franchise" , "Vegetable with tight green flower heads" , "Variety of cabbage, green heads" , "Calabrese" , "A hardy variety of cauliflower" .)
