Which only protect a small area, so drones just need to target less obvious things. Meanwhile your guns shoot birds and once in a while - an occasional bystander. Attackers are always advantaged since you have to protect _everything_ and they only need to target what's left unprotected. Some drones just drop grenades, I somehow don't see your shotgun hitting either the drone (too high) or a grenade (too fast and small).

> Which only protect a small area

We have these things called wheels. Or you could mount it on a drone.

> Meanwhile your guns shoot birds and once in a while - an occasional bystander

We are discussing protecting military bases or military assets.

> Some drones just drop grenades

That requires flying above the target. See counter-point 1.

Please put in the minimal effort needed to follow through at least a few steps of argument and counter-argument in your head. I assure you I am not putting in as little effort into my arguments as you did.
