Arriving in the mountains outside of Ciudad Juárez, Mitchell begins assisting loyalist Mexican Army soldiers, led by Colonel Jimenez, in punching through rebel defensive lines, eliminating artillery, clearing out a rebel camp, and taking out rebel weapon convoys heading for the city. During the fighting, fresh intel from Keating and Lieutenant Barnes, the Ghost's Intelligence Officer, reveals that de la Barrera somehow came into possession of three stolen Ukrainian "Red Star IV" nuclear warheads, and plans to combine them with stolen Pakistani-built "Kashmira-II" missiles, taken from cargo ships in the Panama Canal, in order to strike anywhere in the United States. With this fresh intel deepening the current situation in Juárez, Mitchell continues offering assistance to Jimenez, eventually helping him to secure a heavily defended supermarket. But just as Mitchell's team leaves, disaster strikes when one of the nukes de la Barrera had detonates in the supermarket's basement, killing Jimenez's men just as they were about to search the stronghold, and irradiating the area.
