Refer to soldiers on it abroad (7)
I believe the answer is:
mention
'refer to' is the definition.
('mention' can be a synonym of 'refer to')
'soldiers on it abroad' is the wordplay.
'soldiers' becomes 'men' (I've seen this before).
'abroad' indicates an anagram.
'on'+'it'='onit'
'onit' with letters rearranged gives 'tion'.
'men'+'tion'='MENTION'
(Other definitions for mention that I've seen before include "Speak of - refer to" , "Acknowledge" , "Passing reference" , "Allude to" , "Briefly refer to (something)" .)
