firepower

I'm a little stuck... Click here to teach me more about this clue!

'might' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'i prefer half of wood chopped up?' is the wordplay.
'half of' suggests halving the letters.
'chopped up?' indicates an anagram.
'wood' cut in half is 'wo'.
'i'+'prefer'+'wo'='ipreferwo'
'ipreferwo' anagrammed gives 'FIREPOWER'.

Can you help me to learn more?

(Another definition for firepower that I've seen is " Strength available".)

I've seen this clue in The Telegraph.
