Serdaristan is a small country that shares borders with the Russian Federation and has access to the Caspian Sea there Russia have built large nuclear weapon naval bases. It is controlled by a dictator known as Zavimir Serdar. Most of the citizens of Serdaristan speak Serdish and the country has good diplomatic relations with Russian Federation, but it remained neutral in the Russo-American conflict, although in reality they were secretly working for both sides.
Serdaristan remained neutral in the conflict until Haggard single-handedly attacked it, and Bad Company wreaked havoc, until they were captured by the United States Army to stop them from causing any further hostile actions in the country. Soon thereafter, the squad was sent in to investigate activities in Serdaristan, as the United States was skeptical of where its loyalties lay. Just as soon as the squad's insertion helicopter left off, Serdaristani anti-air positions shot it down, confirming that Serdaristan was no longer neutral. Bad Company pushed through the Serdaristani forces and Legionnaire Mercenaries to finally kidnap the President of Sedaristan and use his golden-plated Mi-24 Hind to go AWOL again and search for the Legionnaire's gold. With this helicopter, Bad Company manages to defeat what was left of the Serdaristan's arsenal, leaving the country to be invaded by the Legionnaire Mercenaries, as the President was exiled to an island in the Caspian Sea, but he returned with an army of Russian and Serdish soldiers with aids from Russia and defeated the Legionnaire Mercenaries forces in the country.
Serdaristan has a small but very advanced and powerful military force with an army, air force and navy for defensive operations. Serdaristan use heavy weapons, heavy armor and other advanced weapon systems from Russia.
