Drones have changed the battlefield. Static trenches are no longer an option.
It's weird that when first world war methods used recently for defense meets Drone warfare It's game over.

Now if only the public would allow Drone hobbyists to fly unencumbered we could train up 1000's of Drone pilots in days. It looks like we are going to need them.

As usual the same mistakes will be made I.e.buying from established weapons manufacturers at huge cost when all we need is an off the shelf cheap Drone with a grenade attached.
