List of soldiers with unit initially (4)
I believe the answer is:
menu
'list' is the definition.
(list of dishes)
'soldiers with unit initially' is the wordplay.
'soldiers' becomes 'men' (men can mean a group of soldiers).
'with' says to put letters next to each other.
'initially' suggests taking the first letters.
The initial letter of 'unit' is 'u'.
'men'+'u'='MENU'
'of' is the link.
(Other definitions for menu that I've seen before include "List of (computer or food) items" , "Choice of dishes" , "Restaurant fare" , "List of options" , "Food programme of restaurant" .)
