All of them, I guess. So the heroes' do more? It's a good thing your dice as bloodthirsty, I should refrain from giving too heavily armoured squads handweapons: it's absolutely terrible if they clash, they can cut at each other for ages and hardly kill anything
(like the heavies and knights in FB)
Do you have homemade rules for using shields in squad vs squad fights? I had to make mine up.
