Cobra VS The Decepticons

Cobra has all their technology, including the nanomites and "Zeus" weapon, VS the Decepticons in Dark of the Moon.

Decepticons can fart out an EMP, so that renders the nanomites nigh useless, along with all other COBRA gear.

Storm Shadow might be able to solo though.

How large is the Cobra force? I don't see why the DEcepticons wouldn't be able to easily mow through the Cobras but it's kind of hard to say because there were times where the military seemed capable of destroying transformers relatively easy and then there were times where the transformers seemed impervious to human weapons.
