Drones have changed warfare at a local tactical level. But your drones and smaller autonomous systems aren't helping if you have overwhelming firepower superiority, ie in Gaza drones haven't inflicted too much damage if you can just drop a couple thousand JDAMS and level out a territory.

Gaza is urban warfare. Most of the drone videos are tanks being attacked in open roads or fields.

I highly, highly , highly recommend you read about the 2002 Millennium Challenge - essentially a war game exercise (and a huge one at that).
