Violent character of the gunners' mob, maybe? (5)
I believe the answer is:
rambo
'violent character of' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'gunners' mob maybe?' is the wordplay.
'gunners'' becomes 'RA' (Royal Artillery).
'maybe?' indicates an anagram (I've seen 'maybe' mean this).
'mob' with letters rearranged gives 'mbo'.
'ra'+'mbo'='RAMBO'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for rambo that I've seen before include "Character relying on brute force" , "28 film hero" , "Senseless violent person" , "Film series hero" , "Stallone tough guy" .)
