Soldiers signed rare novel (10)

I believe the answer is:

grenadiers

'soldiers' is the definition.
(grenadier is a kind of soldier)

'signed rare novel' is the wordplay.
'novel' indicates anagramming the letters (letters in a new or novel order).
'signed'+'rare'='signedrare'
'signedrare' with letters rearranged gives 'GRENADIERS'.
