You know that you need them. Why risk Komrads lives when a drone can gather intel for you?
You have R.C. helicoptors that can carry cameras to hot zone to seek out the undead.
A small RC car can scoot in and out of ware houses without being notice
Find the undead before they find you!
If zombie pop is large, use a larger drone such as a VW bug or truck.
Vehicle can be loaded with weapons that are motion sensitive and blow away zombies like there was no tomorrow.
Vehicle can also be loaded with explosives and be used to take out a zombie hidey hole
like warehouses and other deserted buildings.
Don't give the bastards a place to hide.
Vehicle to be used should be an automatic. Easier to control.
So how are you going to protect your fellow KOMRADS?
