Hunter Force. I think Ironwood would love to do just that. Why he hasn't I don't know maybe Ozpin's holding him back for some reason.

Me personally I don't see why they haven't: Retrofitted every available A/C into "Death for Above" (ref AC130). Gather all A. Knights, A. Paladins, Spider Droids and set out on a coordinated Air Ground offensive labeled "Destroy All Grimm".
