Getting us a ram, I upset Japanese warrior (7)
I believe the answer is:
samurai
'japanese warrior' is the definition.
(I've seen this in another clue)
'getting us a ram i upset' is the wordplay.
'getting' is a charade indicator (letters next to each other).
'upset' is an anagram indicator.
'us'+'a'+'ram'='usaram'
'usaram' after 'i' is 'iusaram'.
'iusaram' with letters rearranged gives 'SAMURAI'.
(Other definitions for samurai that I've seen before include "Traditional Japanese warriors" , "Japanese warrior code" , "Military figures" , "Seven -, film directed by Kurosawa" , "Former Japanese military caste member" .)
