Soldiers confronting wicked troublemaker (6)
I believe the answer is:
menace
'troublemaker' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'soldiers confronting wicked' is the wordplay.
'soldiers' becomes 'men' (men can mean a group of soldiers).
'confronting' says to put letters next to each other.
'wicked' becomes 'ace' (ace can informally mean very good).
'men'+'ace'='MENACE'
Can you help me to learn more?
(Other definitions for menace that I've seen before include "Serious threat" , "ominous atmosphere" , "Threaten with harm or danger" , "A threatening quality" , "Act in a threatening manner" .)
