Different article carried by soldiers (5)
I believe the answer is:
other
'different' is the definition.
(I've seen this before)
'article carried by soldiers' is the wordplay.
'article' becomes 'the' (the 'definite article' part of speech).
'carried by' means one lot of letters goes inside another.
'soldiers' becomes 'or' (Other Rank).
'the' placed within 'or' is 'OTHER'.
(Other definitions for other that I've seen before include "Different, alternative" , "One may be significant" , "Different; additional" , "Throe (anag)" , "Alternate; additional" .)
