as it saw fit. Libya reportedly exported 130 unidentified armored vehicles of Brazilian origin to Iran before 1987. Description The basic layout of all Urutu variants is the same: the driving compartment is located to the front left of the hull, with the engine compartment to the front right and the troop compartment to the immediate rear. The driver is provided with a hatch and three driving periscopes in the sharply angled vehicle glacis. Passengers may debark from doors on either side of the hull or from the rear; they are also afforded four emergency hatches in the hull roof. The troop compartment is fitted with vision blocks and firing ports as standard to allow passengers situational awareness while embarked. An Urutu's hull is composed of two distinct layers of welded ballistic steel able to resist point-blank small arms fire, including 7.62×39mm armor-piercing ammunition. The Urutu was fitted with a 12.7mm Browning M2 heavy machine gun as standard. The machine gun is operated by a gunner seated directly behind the driver in the left of the hull. In all late production models, the gunner's station is also provided with day/night sights with five power magnification and a stadiametric rangefinder. Some of the more common Urutu variants replaced the Browning heavy machine gun with a single turret or pintle-mounted 7.62mm general-purpose machine gun. Depending on the size of the turret ring, it was also possible to fit heavier turrets carrying gun-mortars or low-pressure cannon for direct fire support. Transmission consists of an Allison MT-643 automatic gearbox with five forward and one reverse gear ratios. Early Brazilian Army Urutus used either a Clark manually operated gearbox with the same gear pattern or a manual Mercedes-Benz 63/40 gearbox. The Urutu has an independent double wishbone suspension for its front wheels, but the rear two axles are fitted with a unique boomerang type walking beam suspension with semi-elliptical springs. External Urutus had a very distinct hull with a sharply angled glacis; the front of the hull slopes back to just forward of the rear wheels at 60°. The hull sides are vertical until halfway to the roof line, at which point they slope slightly inwards. Hull doors are visible to the rear of the first wheel station on either side of the vehicle, although the final production run of Urutus produced by Engesa eliminated the door on the right to create a more spacious
