Contingency (mission)

After releasing Captain Price from the Russian gulag, Price carries out a plan to end the war at the United States. Task Force 141 must secure a route to a docked submarine in Russia. Price makes his way to the submarine. The mission begins with you and Price taking out patrols in the woods; follow his instructions to avoid alerting enemy patrols. You will frequently encounter groups of more than two enemies; avoid them as much as possible, but if you must, you need to be fast on the trigger and take them out. The dogs are especially dangerous since they can sniff you out. At one point a BTR-80 will attack you; follow Price into the woods to avoid its fire. You will eventally regroup with the task force and initiate your attack on the sub base. Use your predator missile as much as possible, especially against the helicopter, tanks, and enemies clustered near vehicles and explosives. Get Price to the sub within the time limit, and you will follow ghost to a building where you can defend from the enemies. Ghost warns Price that the sub's missle silo doors are opening, only to learn in shock that it was exactly as he planned. Price initiates a nuclear missile launch with the intent to detonate it in the upper atmosphere as an EMP. The EMP ensures the survival of Sergeant Foley and his men from the 1st Battalion, 75th Ranger Regiment in Washington D.C, but the shockwave destroys the International Space Station.

Trivia

 * The dialogue spoken by Price (to Roach) during the opening section of this mission is very evocative of the dialogue spoken by MacMillian during the Modern Warfare mission "All Ghillied Up". Several of Price's quotes ("Good night", "Beautiful","Don't do anything stupid", etc.) are the same as MacMillan's.
 * At one point, Price says, "These Russian dogs are like pussycats compared to the ones in Prypiat", directly referencing the Modern Warfare mission "One Shot, One Kill".
 * Soap also comments, "Dogs. I hate dogs." This is humorously referring to the many attack dogs you had to face in Call of Duty 4. It could also be a reference to the movie Dog Soldiers, also starring Kevin McKidd as a British soldier.
