Right now, the novelty of the technology means the offensive has an advantage. But long term it will be the defensive who will benefit the most from drones.
I described below how you could launch thousands of them from a single massive container that gets dropped by B2 bombers. You have to use your imagination, you're not limited by today's technology anymore.
