This mission can be skipped due to its disturbing content.

Regional Differences
In the Russian version of the game by 1C Company, this mission is not available for play. In the Japanese and German Versions, if the player kills a civilian, the game will restart from the last checkpoint with a message saying, "You killed a civilian!". In the Japanese version, Makarov's line, "Remember, no Russian" is mistranslated as "Kill them, they are Russians." (殺せ、ロシア人だ Korose, Roshia-jin da?) This was criticized as the plot of the game was centered around the terrorist's motivations and as a result, the mistake caused some confusion. This error was fixed in Call of Duty: Modern Warfare 2 Campaign Remastered.
