Journalist has soldiers to fix (5)
I believe the answer is:
emend
'to fix' is the definition.
(I've seen this in another clue)
'journalist has soldiers' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'has' means one lot of letters goes inside another.
'soldiers' becomes 'men' (men can mean a group of soldiers).
'ed' going around 'men' is 'EMEND'.
(Other definitions for emend that I've seen before include "Modify" , "Correct, revise (text)" , "Improve by altering" , "Edit; make alterations to a draft" , "Make improvements to (text)" .)
