Brigade, the unruly kind (3-7)

I believe the answer is:

big-hearted

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

'kind' is the definition.
Both the definition and answer are adjectives.
Perhaps you can see a link between them that I don't see?

'brigade the unruly' is the wordplay.
'unruly' indicates an anagram.
'brigade'+'the'='brigadethe'
'brigadethe' anagrammed gives 'BIG-HEARTED'.

Can you help me to learn more?

(Another definition for big-hearted that I've seen is " Generous".)

I've seen this clue in The Everyman puzzle in The Observer.
