Wrong about soldiers' anguish (7)
I believe the answer is:
torment
'anguish' is the definition.
(I know that torment has the is a more specific form of the action anguish)
'wrong about soldiers'' is the wordplay.
'wrong' becomes 'tort' (legal term).
'about' indicates putting letters inside.
'soldiers'' becomes 'men' (men can mean a group of soldiers).
'tort' enclosing 'men' is 'TORMENT'.
(Other definitions for torment that I've seen before include "Torture" , "Harass" , "Cause great pain to" , "Cause mental distress" , "More TNT (anag.)" .)
