Soldiers get initially unexciting range of food (4)
I believe the answer is:
menu
'range of food' is the definition.
'soldiers get initially unexciting' is the wordplay.
'soldiers' becomes 'men' (men can mean a group of soldiers).
'get' means one lot of letters go next to another.
'initially' indicates taking the first letters.
The initial letter of 'unexciting' is 'u'.
'men'+'u'='MENU'
(Other definitions for menu that I've seen before include "that can appear on computer screen" , "Food programme of restaurant" , "list of available courses" , "Cafe's list" , "Restaurant fare" .)
