Soldiers attending Kent town for trial (6)
I believe the answer is:
ordeal
'trial' is the definition.
(thesaurus)
'soldiers attending kent town' is the wordplay.
'soldiers' becomes 'or' (Other Rank**).
'attending' means one lot of letters go next to another.
'kent town' becomes 'deal' (I've seen this before).
'or'+'deal'='ORDEAL'
'for' acts as a link.
(Other definitions for ordeal that I've seen before include "Difficult experience, a tough time" , "Struggle" , "A tough and testing time" , "A difficult or harrowing time" , "Trouble" .)
