'drive the enemy out' is the definition.
'force' can be an answer for 'drive' (synonyms). I am not certain of the 'the enemy out' bit.

'drive the enemy out' is the wordplay.
'drive' becomes 'rc' (I can't explain this - if you can you should give a lot more credence to this answer).
'the enemy' becomes 'foe' (foe can mean an enemy or rival).
'out' indicates putting letters inside.
'rc' inserted within 'foe' is 'FORCE'.
