Ordinance in objective?

Hey,
I haven’t been fully keeping up with halo 4 info and I was wondering about ordinance drops in relation to objective games. Have they been confirmed? I mean, it could be annoying in a H:R situation in which you come up against a whole team farming you but it would be an excellent help to a team in a competitive objective match with an overshield or weapon to aid in defense/offense. Thoughts? And preferably proof if it’s been confirmed or denied?
