Coordinated Operation Chihuahua or formerly known as Joint Operation Chihuahua is a Military and Federal Police operation started in 2008 by the Mexican Army and Policía Federal Preventiva. The objective is to "besiege" Ciudad Juárez to concentrate forces and saturate the area to confront the three cartels already operating in the city. Ciudad Juárez is known to be one of the most dangerous cities in the Americas. In the year 2007 more than 100 police officers were killed in Juárez in attacks blamed on organized crime. As a result of drug cartel violence, President Felipe Calderón has previously launched other Joint Operations in other states.^[1]

In 2008, Ciudad Juárez was designated as “The City of the Future” by the prestigious magazine “Foreign Direct Investment” published by the influential “Financial Times group.”.^[2] However, the city is also a site of widespread poverty and violence, including an infamous series of unsolved murders of female factory workers. The violence generated by the war of the drug cartels for control of drug routes translated into some 6,000 killings in 2008. More than 1,600 of them occurred in Juárez, three times more than the most murderous city in the United States. As of July 14, 2009, the body count in Juárez surpassed 1000, which is an acceleration over the year 2008. This mark was not reached in 2008 until over two months later: September 16.^[3]

On December 1, 2006, President Felipe Calderón assumed office and declared war on drug traffickers. Troops and Federal Police forces were ordered to move into hot zones where drug cartels operated—especially in Michoacán, Tamaulipas, and Ciudad Juárez.

The army quickly mobilized two units; the first ground unit composed of 35 soldiers equipped with 4 military vehicles from the 76th Infantry Battalion, the second Air unit composed of 15 personnel from the army's Parachute Rifle Special Forces Brigade equipped with one Mi-17 and an MD 503.
