SEALs ran amok in military stores (8)
I believe the answer is:
arsenals
'military stores' is the definition.
'arsenals' can be an answer for 'stores' (I've seen this in another clue). I'm not sure about the 'military' bit.
'seals ran amok' is the wordplay.
'amok' indicates an anagram.
'seals'+'ran'='sealsran'
'sealsran' is an anagram of 'ARSENALS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for arsenals that I've seen before include "Arms depots" , "Collections of arms and ammunition" .)
