OpFor

OpFor (short for Opposing Forces or Opposition Force) was a paramilitary force that seized power in the Middle East in 2011 following a violent coup d'état. They served as the main antagonists during the first chapter of Call of Duty 4: Modern Warfare in the USMC segment of the campaign.

History
The OpFor, led by Khaled Al-Asad, came to power during a violent military coup in the Capital City, securing its mineral wealth and cementing itself as a major power in the Middle East. Their coup culminated in the dramatic execution of former President Yasir Al-Fulani on national television.

Following their rise to power, the United States Marine Corps invaded the country in an attempt to remove the OpFor from power. Though the search for Al-Asad was unsuccessful, the Americans were able to score multiple victories during their brief military campaign. In just a few days, the bulk of Al-Asad's forces had been pushed back to the Capital City where they were making their last stand. However, as US ground combat forces closed in on the last enemy stronghold, the OpFor detonated a large nuclear warhead, obliterating themselves and all American forces in the vicinity.

It later became evident that the OpFor had been aided by the Ultranationalist rebels in order to draw attention away from the Second Russian Civil War. The Ultranationalists had been supplying the OpFor with equipment, including weapons, vehicles, and, ultimately, nuclear ability.

Following Al-Asad's capture and execution by the SAS in Azerbaijan, it is unknown what happened to the OpFor.

A faction called OpFor also appear in Call of Duty: Modern Warfare 2, based in Afghanistan in the missions "Team Player" and "Endgame". It is possible that they are the same OpFor led by Al-Asad, but it is not completely certain. If they are, it is unknown if they have a new leader or a new set of motives.

Equipment and Arsenal
The OpFor was supplied mainly by Ultranationalist forces. Most of their weapons and equipment are in use by the military of several Middle Eastern nations. Though they are relatively well-known, many weapons available to other factions are not present in the OpFor's armory.

The OpFor in Afghanistan have a relatively better armory, having access to the modernized AK-47, as well as numerous modern attachments. They also seem to have better armor, as they wear military-grade ballistic vests as opposed to blue Kevlar security vests.

They have a large assortment of armed vehicles, with BMP-2 and T-72 tanks, as well as an air force consisting primarily of attack helicopters and gunships such as the Mi-24. During "The Coup", several MiG-29 fighters are also seen. In addition, they also have several infantry fighting vehicles (IFVs).

Call of Duty: Modern Warfare 3
In the multiplayer preview in the Survival Mode trailer, a Modern Warfare 2 style OpFor insignia can be seen above an I.M.S. and in the Modern Warfare 3 map U-Turn, the OpFor insignia can be seen in a tunnel.

Nationality
The nationality of the OpFor is never explicitly stated. The logo of OpFor has the military insignia and flags depicting two crossed swords, similar to the Omani, Saudi Arabian, and 1996-2001 Taliban-era Afghanistan Coat of Arms. Reference to the in-game maps does not provide a conclusion either, as different missions take place in different locations throughout the Middle East. Exposition given by Al-Asad in "The Coup" indicates that the nation was formerly a monarchy before President Al-Fulani was elected. While "Charlie Don't Surf", "The Bog" and "War Pig" take place within the coastal province of Jeddah in Saudi Arabia, the next mission "Shock and Awe" takes place in southern Iraq. This evidence supports the idea that the OpFor nation is, in fact, a fictional Arab Republic, and was created only for story and gameplay purposes. On a television in the mission "Blackout", a news reporter describes it as a "small, but oil rich country". In some scrapped single player levels, such as "Designated Training", the unknown country is specifically called "Saudi Arabia".

The new OpFor in Call of Duty: Modern Warfare 2 fights in Afghanistan. Their relation, if any, to the original OpFor is not known but their major link is that they speak Arabic. There are also posters of Khaled Al-Asad and Call of Duty 4 OpFor logos around the city in "Team Player".

Trivia

 * The OpFor in Call of Duty 4: Modern Warfare have a more professional appearance, with the use of ballistic helmets, bulletproof vests, and other military gear. However, in Call of Duty: Modern Warfare 2, they appear to have less gear and simply wear BDUs, chest rigs, and berets for the most part.
 * In Call of Duty 4: Modern Warfare, Al Asad is the announcer for multiplayer OpFor. In Call of Duty: Modern Warfare 2, it is a different unidentified voice.
 * In Call of Duty 4: Modern Warfare multiplayer, if the player plays as OpFor, he will always wear gloves in first-person, even if third-person character has no gloves.
 * The multiplayer model for OpFor soldiers in Call of Duty 4: Modern Warfare (DS) is similar to Al Asad, aside from lacking his sunglasses.
