cobra

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

'emergency council' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'company support' is the wordplay.
'company' becomes 'co' (abbreviation).
'support' becomes 'bra' (a support for the breasts).
'co'+'bra'='COBRA'

Can you help me to learn more?

(Other definitions for cobra that I've seen before include "Sinuous creature" , "Poisonous snake" , "One with hood" , "Deadly snake called King" , "crisis response group" .)
