   EE-3 "Jararaca" light wheeled armored reconnaissance vehicle was developed by Brazilian company "Engesa" at the end of 70-ties. Vehicle is intended for reconnaissance and patrolling.

   "Jararaca" is equipped with radio set, night vision device, fire-extinguishing means. It can be additionally fitted with Nuclear Biological Chemical protection system.

   On EE-3 base there were developed self-propelled anti-tank missile complex "Milan" and chemical and radioactive reconnaissance vehicle. There were built "Jararaca" variants fitted with 7.62-mm machine gun, 20-mm automatic gun, 60-mm grenade launcher, or 104-mm recoilless gun.
