Max post-apocalyptic action multi-media franchise. The allied Free Syrian Army rebels have also been reported to have fashioned similar makeshift armoured fighting vehicles. Battle of Marawi During the Battle of Marawi, the ground forces of the Philippines' Army and Marine Corps used wooden armour plating on their armoured personnel carriers such as the GKN Simba, V-150, M113A2 and Marine LAV-300 FSV/APC to protect against rocket propelled grenades fired from the Maute and Abu Sayyaf terrorists in the city. Non-military use During the 1984 UK miners' strike, buses used for transporting strikebreakers to work were armoured against attacks by strikers by fitting metal bars to their windows. These improvised armoured buses were nicknamed "battle buses". In recent years, some storm chasers in the United States have developed purpose-made vehicles, such as the Tornado Intercept Vehicles designed to survive the hostile environment inside a tornado. These vehicles are built on truck and SUV chassis with heavy armour shells built onto them consisting of steel, kevlar, polycarbonate, and Rhino Linings to protect against airborne debris. Drug cartels involved in the Mexican Drug War have in a number of cases fitted improvised armour to heavy trucks. In the Marvin Heemeyer incident, a disgruntled man built an improvised armoured bulldozer and attacked buildings and police. The machine used in the incident was a modified Komatsu D355A bulldozer, fitted with makeshift armour plating covering the cabin, engine, and parts of the tracks. In places, this armour was over thick, consisting of 5000-PSI Quikrete concrete mix fitted between sheets of tool steel (acquired from an automotive dealer in Denver), to make ad-hoc composite armour. This made the machine impervious to small arms fire and resistant to explosives: three external explosions and more than 200 rounds of ammunition were fired at the bulldozer and had no effect on it.
