EE-9 "Cascavel" armored reconnaissance vehicle was developed by Brazilian company "Engesa" alongside with EE-11 armored personnel carrier. Both vehicles have a number of common parts and devices. EE-9 serial production began in 1974 and since 1975 vehicle was supplied to Brazilian Armed Forces and exported to a number of countries. It is used by Bolivian, Columbian, Chile, Qartar armed forces. Some African, Near East, and Asian countries show interest to obtain such vehicle for their armed forces. Vehicles success in world weapon market is determined by its high simple and reliable design, ability to use "Cascavel" for reconnaissance, or support infantry, and fight against enemy main battle tanks.

"Cascavel" is built using main battle tank arrangement scheme. Engine compartment is placed in the rear part of the hull, combat compartment - in the middle, and driving compartment is placed in the front. Vehicle crew consists from driver, commander, and gunner.

The hull and the turret are made from welded multi-layer armor, developed by "Engesa". Such armor is made from two layers of steel: external layer is rigid, while internal layer is less rigid, but more tough. Brazilian research showed that such armor design increases vehicles armored defense. Such defense additionally protects crew from vehicles armor shells, appearing after direct hit of anti-tank gun, guided missile, or grenade launcher. Frontal armor plates are made from 16 mm armor and defend vehicle from large caliber machine guns. Other hull parts defend vehicle against firearms bullets, artillery projectiles and small caliber mines shells.

Reconnaissance vehicles main armament is placed in a two seat armored rotating turret, placed in the combat compartment. EE-9 Mk.II vehicle, used with Brazilian armed forces is fitted with 37-mm gun, while export modification Mk.III has turret mount with 90-mm gun, used in French Armored Reconnaissance vehicle AML-90. Recently produced standard EE-9 Mk.IV has EC-90 half automatic 90-mm gun produced in Brazil under license. Main gun is reloaded manually. It's rate of fire is 6 rounds per minute. It has elevation range from -8 to +15. Main gun fires two type simple projectiles: with armor-piercing or High Explosion Fragmentation combat elements. However it is possible to fire armor-piercing-cumulative projectiles with compressing warheads fitted with plastic explosives, smoke, fragmentation or case-shot projectiles, fitted with sparrow shape combat elements. Vehicle's combat load consists from 44 projectiles. 12 of them are placed in the turret, while the others are in the hull.

Additional armament consists from coaxial 7.62-mm machine gun, mounted in the turret, 12.7-mm anti aircraft machine gun and smoke grenade launchers, placed from the both sides of the turret.

Vehicle commander and gunner both can execute fire from the main gun. Commander's seat is placed left from the main gun and gunners - right. They both use combined day and night periscope sight. Vehicle commander additionally is equipped with day and night panoramic sight.

Gunner has one periscope observation device, while commander use three similar observation devices, built-in in his turret. "Cascavel" is fitted with laser rangefinder, placed on the main gun. "Engesa" company is recently developing a stabilized in both planes fire control system, which will allow execute sighted fire on the move.

EE-9 "Cascavel" armored reconnaissance vehicle EE-9 "Cascavel" modifications Mk.II, III, IV are powered by 6V-53N V-type 6-cylinder engines, developed by "Detroit Diesel". Engine has maximum power of 212 h.p. Vehicle modifications Mk.V, VI, VII are powered by OM352A 190 h.p. diesel engines, developed by "Mercedes Benz". All modifications are fitted with the same MT-643 automatic hydromechanic transmission, developed by USA company "Allison".

"Cascavel" chassis is based on 6 x 6 wheeled formula. Vehicle use wheels with 14.50 x 20 mm dimensions. Frontal wheels have independent suspension, based on springs and hydraulic absorbers. Rear both axis are tightly connected using "boomerang" principle. Rear axis pare has a large vertical step in 0.9 m. Wheels are fitted with centralized air pressure system allows to increase significantly overall vehicle cross-country performance. "Cascavel" manages 0.6 m vertical step, 1 m wide trench and 1 m depth water obstacle. Vehicle has no movement on water abilities.

EE-9 has a maximum road speed in 100 km/h.

Mainly it's internal equipment depends from customer requirements. Standard vehicle variant is fitted with radio set, tank communication device, fire-extinguishing sources. There is ability to place Nuclear, Biological, Chemical protection system, air conditioner or heater.

EE-9 "Cascavel" armored reconnaissance vehicle was used in combat actions by Iraq Armed Forces during the Gulf War.
