According to page 92 of the Ork codex: "A model with an ammo runt is allowed to re-roll one to hit roll for a shooting attack, once per game." If this is the case, then why does Kaptin Badrukk have three of them that are "seperate from the ammo runts allowed by his unit"? Doesn't it say that a model with an ammo runt may only re-roll once per game? Either I'm reading this wrong, or the other two are just useless.
EDIT: Thanks for the feedback. Problem solved. There is however, one last ammo runt related rules question that I still harbor. That being: can a Big Mek with a Shokk Attack Gun use the ammo runts in a Big Gunz battery if he's part of the crew? I'm thinking yes, but I'd like to confirm.
