The Grimm air drop is probably to replace the Breach, which Roman set off early after RWBY stumbled on his operation. It wouldn't suprise me if they have fewer than they planned inside the city itself due to the fact they've had to bring a finite number in via Bullhead rather than just open a hole for an indefinite number to enter.

That said, the way the Grimm all started charging, as if they knew their time had come? Either Cinder has some link with them or she's actually leading one side in a three-side war and is about to learn that she neither has a monopoly on evil nor is even a particularly big bad.
