The EE-9 Cascavel (Portuguese pronunciation: [kɐʃ.kɐ.ˈvɛɫ], translated to Rattlesnake) is a six-wheeled Brazilian armoured car developed primarily for reconnaissance. It was engineered by Engesa in 1970 as a replacement for the Brazil's ageing fleet of M8 Greyhounds. The vehicle was first fitted with the Greyhound's 37mm main gun and subsequently with a French turret adopted from the Panhard AML-90.
