Badge of soldier coming back inside inn as I ordered (8)
I believe the answer is:
insignia
'badge' is the definition.
(insignia is a kind of badge)
'soldier coming back inside inn as i ordered' is the wordplay.
'soldier' becomes 'gi' (government issue or general issue).
'coming back' shows that the letters should be reversed in order.
'inside' indicates putting letters inside.
'ordered' is an anagram indicator.
'gi' back-to-front is 'ig'.
'inn'+'as'+'i'='innasi'
'innasi' is an anagram of 'insnia'.
'ig' going into 'insnia' is 'INSIGNIA'.
'of' is the link.
(Other definitions for insignia that I've seen before include "Badges of office" , "Stars and stripes, say" , "arms" , "Distinguishing emblem or badge" , "military mark" .)
