Kit found in poor European army unit (7)
I believe the answer is:
brigade
'army unit' is the definition.
(I know that brigade is a type of army unit)
'kit found in poor european' is the wordplay.
I cannot quite understand how this works, but
'kit' could be 'rig' (I've seen this before) and 'rig' is found within the answer.
'poor' could be 'bad' (similar in meaning) and 'bad' is present in the remaining letters.
'european' could be 'e' (abbreviation e.g. EU) and 'e' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for brigade that I've seen before include "Abridge (anag)" , "Military group" , "Body of troops" , "Part of an army division" , "Set of troops" .)
