Having responsibility in attack (2,6)

Ross

I believe the answer is:

in charge

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

'having responsibility' is the definition.
I can't tell whether this defines the answer.

'in attack' is the wordplay.
'attack' becomes 'charge' (charging is a kind of attacking).
'in'+'charge'='IN CHARGE'

Can you help me to learn more?

(Other definitions for in charge that I've seen before include "Taking command" , "Managing" , "At the helm" , "Having overall control" , "as a responsible person" .)

I've seen this clue in The Irish Independent and The Globe and Mail.
