I have four, and maybe later a fifth, post apocalyptic army planned, The Law, The Creepers, The Road Warriors and The Survivalist.
Here is the Stronghold for my Road Warrior army. Yes, it is very much influenced by the Mad Max movies, and the Stronghold obviously from Fury Road. This one involves several very involved conversions. The models are Pendraken 10 MM, and the war Rig, called "The Green Dragon" was made from a 1920/30's SCW truck. The wrecked and rusted out SUV was a WWII British staff car. All of my Stronghold bases are 60 x 80 MM.
