Suspicious soldier with no papers (8)
I believe the answer is:
paranoid
'suspicious' is the definition.
(I've seen this before)
'soldier with no papers' is the wordplay.
'soldier' becomes 'para' (short for paratrooper).
'with' says to put letters next to each other.
'papers' becomes 'ID' (identification papers).
'para'+'no'+'id'='PARANOID'
(Other definitions for paranoid that I've seen before include "Excessively suspicious" , "Afflicted with delusions of persecution" , "mental disorder" , "Distrustful" , "one given to suspicion" .)
