Military commander has some bag handlers (4)
I believe the answer is:
agha
'military commander' is the definition.
(historical title in the Ottoman Empire)
'some bag handlers' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'AGHA' can be found hidden inside 'bag handlers'.
'has' is the link.
(Other definitions for agha that I've seen before include "Turkish officer" , "Turkish civil or military leader" , "Ruler" , "Alternative spelling for a Turkish commander" .)
