'take gun' is the definition.
The definition and answer can be both related to competing as well as being verbs in their base form.
Maybe there's an association between them I don't understand?

'diane's wing' is the wordplay.
'diane's' becomes 'di's' (short for Diane).
'wing' becomes 'arm' (both can mean a side).
'dis'+'arm'='DISARM'

'from' acts as a link.

Can you help me to learn more?
