What is the name of the controversial mission in Modern Warfare 2?

The controversial mission in Call of Duty: Modern Warfare 2 is called “No Russian.” It is the fourth mission of the 2009 game and takes place at Zakhaev International Airport in Moscow.

The player controls CIA operative Joseph Allen, who is undercover inside a terrorist group led by Vladimir Makarov. Makarov’s group launches a mass shooting against civilians, intending to frame the attack on Americans and provoke a war between Russia and the United States. The mission’s title refers to Makarov’s instruction that the attackers speak no Russian.

“No Russian” became one of gaming’s most debated missions because it allows the player to witness or participate in violence against civilians. Players can avoid shooting, and the level can be skipped without a penalty. Several international versions edited or removed it, while others added restrictions on harming civilians. Crew Expendable, Cliffhanger, and All Ghillied Up are memorable missions from other Call of Duty titles, not the answer here.
