After Haggard single-handedly attacked the neutral nation of Serdaristan, B-Company goes AWOL and trespasses into the country. The squad eventually infiltrates the President's private golf course and palace, where they take Serdar hostage and order him to let them use his private gold-plated Mi-24 helicopter to exit the country and pursue the Mercenaries for their gold. The helicopter is eventually shot down by the Legionnaire and crashes at an unknown location in Russia. Later, Preston Marlowe searches and finds his squad just after the crash. Together they rescue Serdar right before he was about to be executed by the mercenaries. The squad eventually make their way to a small island in the Caspian Sea, where they leave him before they head off towards a small resort city in the Middle East.
- Serdar seems to be a very humorous and nonchalant character, never seen being worried or angry at Bad Company, despite all the things they do to him and his country.

- After destroying the communications station in Air Force One, Serdar states that his "love life is over!" This hints that he participated in online dating services.

- Serdar has a golden AEK-971 displayed in his safe-room.
- Serdar's catchphrase seems to be "Harsh, but fair," as he says it several times throughout the campaign.

- The President owns a personal Mi-24 helicopter gunship. It has a gold-plated exterior, hot-tub, disco ball and a portrait of Serdar in the interior. However, the hot tub and disco ball don't actually appear in the helicopter's interior, only the portrait.
