Watermelons, ceramic plates, coconuts and gas cans are good to shoot your riffles like M16, AK47, PKM machine guns, pistols, RPD, T97 and CKC’s bullets
Gas Tanks is good to go with your riffles like M16, AK47, PKM machine guns, RPD, T97 and CKC’s bullets and RPG (bazooka or well known as Rocket Launcher) and if the rpg hit the target of the gas tanks then the flame and explosion is greatly huge than your expectations
Car, House and Tuk Tuk is a very need to add fueled barrels and or gas tanks in there
