Promotion for leading soldiers reaching junction (11)
I believe the answer is:
advancement
'promotion' is the definition.
(synonyms)
'for leading soldiers reaching junction' is the wordplay.
'for leading' becomes 'advance' (I can't explain this - if you can you should give a lot more credence to this answer).
'soldiers' becomes 'men' (men can mean a group of soldiers).
'reaching' says to put letters next to each other.
'junction' becomes 't'.
'advance'+'men'+'t'='ADVANCEMENT'
Can you help me to learn more?
(Other definitions for advancement that I've seen before include "headway" , "getting on" , "making progress" , "Process of developing" , "Promotion in rank" .)
