Modern Warfare 2 References?

Bad Company 2 dialogue pokes fun at rival game Modern Warfare 2's mission 'Cliffhanger' . Only those who have played will understand.

#1 "No no no. They'll just send some special ops douche bags with pussy ass heartbeat monitors on their guns instead of us." Sweetwater referring to the attachment that Roach uses to infiltrate a Russian base with Soap. 

#2 "It's not a snowmobile. Snowmobiles are for sissies." Sarge referring to the mode of transport used by Roach and Soap to escape the Russian base.

First video shows the gameplay dialogue. Second video shows the 'Cliffhanger' mission.

Bad Company 2's final mission 'Airborne' is also similar to a COD 4 mission 'Mile High Club'. Both take place on an airliner and both teams escape by jumping out of a hole blown in the aircraft.
