No Russian

"Remember... No Russian"

- Makarov

 is a campaign mission in Call of Duty: Modern Warfare 2. It features Joseph Allen under the alias Alexei Borodin working alongside Makarov as an undercover mission to earn Makarov's trust.

Walkthrough
The level begins as your character, Alexei Borodin, in an elevator with Makarov and three other gunmen. You will walk slowly out of the elevator to a security checkpoint where all the gunmen, yourself included, open fire on the civilians. You are restricted to a cruel, casual walk through the airport. Sprinting is enabled but it lets you go at a hurried pace instead of a sprint. For the first half of the level, you utilize your M240 and M4A1 to cause as much destruction as possible. Halfway through the level, the Russian authorities in the form of the FSB arrive on the runways. The M203 and grenades can make short work of them if they have riot shields. As you fight your way through, follow Makarov's lead until you go through a hallway into an ambulance. Whether or not you step in, Makarov will shoot you with an M9 and leave you to die while the FSB discovers your American corpse, inciting a war between the US and Russia.

Trivia

 * This level has been cited to be one of the most controversial missions in gaming history due to killing civilians as part of an objective, so much so that there is an option to skip the level when the game is first begun.
