of firing 600 rounds per minute and a bank for TOW anti-tank guided missiles. This variant was developed for the United Arab Emirates; it could also be fitted with MILAN anti-tank guided missiles as needed. EE-11 Cargo Transporter: Urutu designed as a general transporter for hauling or towing heavy loads. This variant had an internal load capacity of up to 2,000 kg. EE-11 Command and Control: Urutu modified to carry additional radio equipment. EE-11 Air Defense: Urutu carrying twin 20 mm autocannon in a French-designed Electronique Serge Dassault TA20/RA20 turret. There were also Urutu prototypes modified to carry turrets armed with twin general-purpose machine guns, twin heavy machine guns, a CM60A1 gun-mortar, or a single HS804 20 mm autocannon. Colombian derivatives During the early 1990s, Colombia began seeking a domestically produced replacement for its Urutu fleet. The decision to acquire a uniquely Colombian armored personnel carrier was made because it saved hard currency and promoted local industry; with Engesa's closure, Colombian officials were also concerned that parts for the Urutu series would become increasingly scarce and expensive to source in the future. In 1993, Colombia produced a single prototype designated El Zipo, which was essentially a simplified Urutu rebuilt with local parts. Between 1996 and 2003 three more prototypes were built and designated Aymara. The program was shelved after the Colombian Army rejected the Aymara in favor of the Dragoon 300 to complement the Urutus remaining in service. At least one prototype was retained for training purposes, while another may have been converted into an explosive ordnance disposal vehicle. The Colombian Urutu derivatives shared the same transmission, electrical system, and engine of the baseline Urutu but utilized a four-wheeled chassis which eliminated the vehicle's articulated boomerang suspension. Their hulls were externally identical to that of the Urutu, retaining the same hatch and door configuration; however, the interior dimensions were different. For example, the engine compartment of the Aymara was located in the center of the hull rather than at the front and to the right like the Urutu. The prototypes were all at least five tonnes heavier than the standard Urutu and lacked amphibious capability.
