If this tactics character does not exhaust to defend, can it defend multiple enemy attacks during a single turn?

As in if there are 5 mooks with 2 attack each, does this guy defend all 5 for 5 cards from my hand?

Thanks for any responses

Yep.

I approve of this use of "mooks."

Mooks... I looked it up! LOLOL!!!!
