No Russian

"Remember - no Russian."

 is a campaign mission in Call of Duty: Modern Warfare 2. It features Pfc. Joseph Allen (under the alias Alexei Borodin) working alongside Vladimir Makarov as an undercover agent to earn his trust.

Walkthrough
The level begins with the player as Joseph Allen pretending to be Alexei Borodin in an elevator with Makarov and three other gunmen. Makarov tells everyone not to speak in Russian, and they instead speak in English throughout the level. When the elevator opens, they walk slowly out of the elevator to a security checkpoint where all of the gunmen (although the player can abstain) open fire on the civilians. The players movement speed is restricted to a casual walk through the airport. Sprinting is enabled, but it barely increases movement speed. For the first half of the level, the player utilizes the M240 and the M4A1 to cause as much destruction as possible. The only threat in this part of the level are the police officers, though the other terrorists will kill them easily regardless of the player. Halfway through the level, the Russian FSB arrives on the runways. The M203 and grenades can make short work of them if they have riot shields. Flanking them is also an effective tactic. Makarov leads Allen to the getaway vehicle, an ambulance, but shoots him and leaves him to die there. The combination of American weapons and equipment, English-speaking shooters who use military slang, and the body of an American soldier make the attack appear to have been carried out by military trained American terrorists, setting the scene for the eventual Russian invasion of America.

Tips

 * There are no achievements or trophies associated with this level because it can be skipped.
 * If the player walks in front of any of the terrorists' fire, they will not stop shooting and will kill or injure the player.
 * After two friendly fire incidents, the terrorists will turn on the player. Flashbangs also count as friendly fire.
 * Attempting to shoot at the civilians in the metal detector further away from the player will not work, as there is an invisible barrier that disappears after the initial massacre.
 * One of the guards that Makarov shoots near the metal detectors will drop a single M9, while guards further down the map may drop akimbo M9s. It is also possible to pick up Akimbo Red Dot Sight TMPs from guards.
 * It is possible to use the elevator that has not been destroyed.
 * Firing an M203 grenade right behind the center of the first wave of riot shield enemies will kill most of them and cause others to stumble, making them easy targets.
 * During the latter part of the level there are a number of vehicles carrying Riot Shield FSB. Quickly firing M203 grenades on the vehicles can make short work of them.
 * If the player runs past the last group of FSB and hides at the door leading to the extraction point, Makarov will verbally scold Allen for being a coward. If enough time passes, he and the remaining allies will run to Allen's location and kill him, causing an immediate game over with the explanation that Makarov has discovered his identity as a CIA agent.
 * If the player tries to move too far from the building while fighting the FSB, they will be fired upon by an MH-6 Little Bird hovering over the runways.
 * The player can shoot down the transport helicopters with any automatic weapon or launcher.
 * Save the grenade launcher for the FSB.

Regional Differences
This level has been cited as one of the most controversial levels in video game history due to its depiction of acts of terrorism and mass murder carried out by the player. Although many games have allowed the shooting and killing of civilians, such as the Grand Theft Auto series, Modern Warfare 2 is the first game to put the player in control of a gunman during such a civilian-dense terrorist attack. There is an option to skip the level at the beginning of the game at no penalty to the player. Also, if one wishes to play the level but would like to skip it half way through, there is an option at the pause screen saying skip level. It will then ask you if you are sure, saying 'disturbing content notice'. It should be noted that there is no on-screen prompt given to the player to shoot civilians (i.e. the objective is: "Follow Makarov's lead"). In the Russian version of the game by 1C (available for sale not only in Russia, but in Ukraine and other CIS countries), this level is not available for play. In Germany, the mission is aborted if the player attacks a civilian. In the Japanese version, Makarov's line, "Remember, No Russian" is translated as, "Kill them all, they're Russian." This may be due to the Japanese publisher erroneously interpreted the "Russian" in Makarov's line to be referring to the Russian people instead of the Russian language.

Trivia

 * An theory that could explain why Makarov knew about Allen was because Shepherd could have hired Makarov to start the war in the US, thus giving him limitless funds and soldiers to "fight Makarov". This could also explain why Makarov knows where Shepherd is in "The Enemy of my Enemy" and why he wants Shepherd dead.
 * The name "No Russian" appears to have four meanings. It can be a reference to the slow speed the player moves at, as in "No Rushing". It can also mean how Russian is not to be spoken during the assault due to the fact Makarov wants to hide their identity. It can mean that Makarov intends to have "No Russian" left standing at the airport. Finally, it could mean that, as an undercover American, the player was "no Russian".
 * This level was the basis for the first teaser trailer for Modern Warfare 2, where the #2 indicating the floor where you start is also the number in this game of the series. Also noted is that the PA system announcer in the trailer speaks English, although the setting takes place in a Russian airport, suggesting the level was originally planned to take place in a US airport. In this trailer, Makarov seems to be voiced differently when he differently says "Remember - no Russian".
 * At the very beginning of the level, before the player gets to see anything, the phrase Makarov says in Russian is "S nami Bog" (Ru: С нами Бог), which translated to English is "God is with us."
 * When Allen and the terrorists walk through the metal detectors, they will beep and light up. This also happens in the multiplayer map based on this mission, Terminal.
 * As Makarov and his men walk down the stairs towards the Departures board, the player can watch as all of the flights listed switch their statuses to "Delayed." This is most likely an attempt at dark humor by Infinity Ward. Another explanation could be that the airport was put on lockdown because of the attack, thereby delaying flights to and from the airport.
 * Oddly, the Departures board features a delayed flight to Moscow - the very city in which this level takes place. Even though Moscow does have more than one airport, flights do not normally take off from one airport in a city and fly to another in the same city.
 * One of the delayed flight is number 1337, which is internet slang for Leet, or "elite".
 * There is an airplane with a flaming engine, you can walk right through it and suffer no damage. In real life, getting that close to an active jet engine can be lethal.
 * This level has the most teddy bears out of all the levels. Two are found near wounded (or dead) Russians and several are located throughout the shop near the elevators. Large, medium, and small teddies are everywhere.
 * If you shoot Makarov or his guards (more than once), their names turn from green to red.
 * The Russian Police Officers in this level use TMPs, which is odd considering this takes place in 2016, when all Low Level Law Enforcement Officers in Russia are to have transitioned to the PP2000 by 2011.
 * There is a Burger Town in the airport, one of the restaurants featured in the level "Wolverines!"
 * All of the men (besides Makarov) have tattoos of the Russian Insignia on their necks. There is a dead soldier in Exodus with the same tattoos.
 * The cars the police arrive in are Second Generation Ford Crown Victorias, which is inaccurate since the Moscow Militsiya only has First Generation Models, and very few at that, with the bulk of their Vehicle inventory being Ford Focuses and various Russian Brand of cars
 * If you can get close enough, the fire trucks on the runway have no Russian markings.
 * Although both Lev and Kiril are scripted to die, how they die varies from playthrough to playthrough.
 * The telephone number on the emergency ambulance at the end of the level is 04, however in Russia it is 03.
 * The only terrorists to survive this mission are Viktor and Makarov. You can kill the rest of the squad, but Makarov cannot die.
 * Once Makarov tells you all to go downstairs to move onto the airfield, if you take too long and go back to where you started, Makarov will eventually say, "I have no patience for cowards," and then he will come to kill you.
 * A very fun trick is to grab a riot shield, from a killed officer and melee Makarov. One hit should set him off. But just always keep looking at Makarov and he will follow you around shooting your shield, with no effect. As long as you DON'T turn away from them or you will die very quickly.
 * The door closes behind you once you reach the ambulance, trapping you in the room and forcing you to get killed by Makarov.
 * Only certain guards drop usable M9's. Other guards may have a side arm that the player is not able to pick up, this is also seen in the Museum level.
 * If you return to the last checkpoint after coming out of elevator, you will hold your M240 with one hand for few seconds like some other of the 'squad'
 * If you look inside the elevator where you start, where you would push the button to decide what floor to go to on the right side, there is 'IW' for Infinity Ward scratched into the wood.
 * Out of the several stores on the top floor, there is an alcohol store filled with whiskey. If you go to the front counter of the store, there will be 2 game cases with Cpt. Price on the front cover, and features the same back cover as seen on the back of the Call of Duty 4 case.
 * When you ambush the civilians, you can see them run upstairs like soldiers.
 * It seems that Makarov and his crew do not need to reload when firing hundred of rounds at the civilians or at you.
 * You will be shot by Makarov at the end no matter what. If you are near, let Makarov get into the ambulance, and then try to get in, Makarov will help you but will fire a shot through your head and you will fall to the ground. If you are farther back, Makarov will simply get into the ambulance, pull out a pistol and shoot you from there. Even if you run down the hallway and go round the corner where you can't see him, his bullet still somehow goes through the wall and kills you.
 * Throughout the level, you can see Makarov casually shooting civilians and police officers with his M4A1 and even his Thumper held in only one hand.
 * If the player shoots the ambulance at the end of the level, even once, the terrorist waiting inside will die as the bullet ravels seemingly unimpeded by the door. After this Makarov will turn on the player, killing him.
 * Sometimes Viktor will start to look like he is getting hurt and will even fall to the ground and get up, even if there are no enemies around.
 * This is the only time in the Call of Duty series where you can kill as many civilians as you want without failing the mission.
 * If you shoot the Cash Registers, they will explode and eject money, though there appears to be a developer oversight as the money is based on U.S. dollars.
 * All the books in the bookstore on top of the stairs have English writing on them despite being in a International Airport, some of the books should at least be in Russian
 * Next to some of the cash registers you can see a mug with the picture of a girl printed on it. These can also be seen in Call of Duty 4, most easily spotted on the doors cutaway in the armour on the level F.N.G.
 * Although Allen is blamed for killing the civilians as being the only American no suspicion is raised by the two dead Russians that were part of Makarov's team. This might be because they could be mistaken for citizens, but their weapons and equipment make that unlikely. It can be explained in that Makarov obviously knew Allen was an American (and judging by the reactions of Viktor and the ambulance crew, as did the rest of his squad) and gave all the participants American identification. Another factor could be the ultranationalist government just looking for a reason to fight America, or possibly even Shepherd pulling strings again.
 * Makarov must have planned the attack route impeccably as despite the numerous security cameras that must have been present in an important facility such as an international airport (a picture of which can be seen in the "mission select" screen), none is able to capture a clear image for him to be identified.
 * After the police arrives to the airport and everyone starts speaking in English, there is a part where they start shooting from a window in the second floor of the airport and some of the terrorists say "Contact, second floor window!" and one of them replies saying "Copy that, second floor windows!" with a clear American accent. It is possible that Allen says this. This could have been part of the plan to make people think it was an American attack. Also, when Viktor says "I've waited a long time for this", he speaks with a slight American accent as well.
 * If you look at the white and red barriers, if you look closely, you can see "Property of IW Inter. Airport."
 * If you're quick enough, you can see a member of the squad slaughtering the civilians which are under the elevator, and the blood you see when you come down magically appear
 * You will notice that the elevator floor on the second elevator becomes a ghost figure when you take it down to the first floor (departure) and you can crawl under it.
 * When you get to the fighting, go back into the airport and head to the elevator. If you haven't taken it to go to the bottom floor before, go in it now and you should fall down the the bottom. Once down you will be trapped, and after while Makarov will say "I have no patience for cowards" and shoot you from outside the airport even straight through the bulletproof glass.
 * Using a PC cheat, the player can see that the name of the Ambulance driver is "Thumper," which also happens to be a name for an American vehicles in Team Player mission.
 * You can use the elevator on the right, there is a terminal next to the elevator that say "Press X for Elevator" and the elevator will come up.
 * Why Allen isnt wearing gloves is unknown, as the rest of the squad does. Odder is the fact that this is the first time in the Modern Warfare series where the controlled character isn't wearing gloves.
 * If you look closely, the parked aircraft resemble a Boeing 727. The first aircraft is numbered 727, the second 737, and the stairs next to the second airplane(the "737") are numbered 757. This is a reference to the Boeing aircraft model numbering system.
 * For the briefing in Takedown, many pictures of Makarov and his team can be seen. This is very strange, as then airport security or FSB who arrive after Makarov leave would have of course investigated the photos and videos, and should have identified Makarov. It is impossible of Makarov to have been unidentified, as then he was very famous in Russia. Also, the Mission Select menu picture for No Russian shows Makarov and his team (obviously, Allen was not shown) firing at the civilians just after the player exits the first elevator. This means that the FSB or whoever was investigating at the time, was working with Makarov, or were bribed to not release the findings. It seems that Task Force 141 were able to receive the images, but it is unknown why they didn't show the world the findings.
 * It should also be noted that the only pictures of Makarov's face seems to be in the CIA archive. Ultranationalist leaders are not very photogenic, as evidenced by the lack of knowledge of Zakhaev's involvement in the Middle Eastern coup despite him standing only several feet from the camera's view during Al-Fulani's execution.
 * Since Russia declared war on America after the incident, it is unknown what happened to any Russian civilians in America. Most likely, America would send them to Russia, as America themselves have no intention of fighting the war at an offensive level rather than a defensive level.
 * When you fight the first group of FSB on the runway, one of them will drop a unique F2000 assault rifle that is not found anywhere else in the game, including multiplayer. Simply called "F2000 Scope", it is nothing special but it is the only weapon in the entire game seen with this unique scope, though it closely resembles the Mars Sight scope. The scope is one of the F200's variant's attached standard scope.
 * Sometimes one of the civilians looks like Raptor from "Wolverines!".
 * At the end of the level there is a glitch where the player can shoot the ambulance's doors and kill the Russian (Anatoly) inside. His body will drop out of the ambulance, and Makarov will oddly not turn on the player.  Instead, the scene will continue as intended, Makarov will appear to be helped in to the ambulance by nothing (the conversation between him and Anatoly is not triggered) and then proceed to shoot Allen.
 * The signature Modern Warfare "2" logo is seen in the elevator in the beginning of the level.
 * It is unknown how Makarov and the others got into the airport in the first place.
 * The guards in the airport are not realistic, most of them don't have dogs nor metal detectors.
