Sergeant Paul Jackson was an operator of the USMC 1st Force Reconnaissance Company and one of the three playable characters in Act 1 of Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare Remastered. The other playable characters in Act 1 are John "Soap" MacTavish and President Yasir Al-Fulani. He was also one of the 30,000 U.S Marines killed in the nuclear explosion in the capital city that was triggered by Vladimir Makarov.
Sgt. Paul Jackson and the 1st Force Recon of the USMC were sent to the Middle East in search of Khaled Al-Asad. They entered the country in numerous Black Hawks. Jackson's platoon, led by Lt. Vasquez, landed in a coastal town and headed to the local OpFor Headquarters where they believed Al-Asad is hiding. After the search of the HQ proved unsuccessful, Vasquez was informed by Command that Al-Asad was broadcasting in a TV station not far from their position. The Marines pushed through the town easily eliminating OpFor resistance. Once inside the station, they regrouped with SSgt. Griggs and his squad before clearing the broadcast room. Unfortunately, Al-Asad was not there either and the Marines headed out to continue the search.
The USMC forces continued their push towards the capital in pursuit of Al-Asad. Lt. Vasquez was given orders to help protect an Abrams tank - callsign "War Pig" - which was stuck in a Bog. The Marines moved out and managed to eliminate OpFor troops in an abandoned building before destroying OpFor tanks and infantry who were moving along an overpass. They managed to reach "War Pig" on time and stopped it from being overrun by the OpFor. Vasquez requested air-support but his request was denied due to a ZPU in the vicinity. Jackson headed out and destroyed the ZPU, allowing two Cobras to come in and finish off the enemy. A few hours later, War Pig managed to escape the bog and provided support for the Marines. They headed through the city and (with the help of War Pig) reached the LZ for extraction.
Jackson was then part of the strike force sent to the capital city to capture Khaled Al-Asad. He was the Mk19 gunner aboard a Sea Knight helicopter - callsign "Outlaw 2-5" - and provided air support for Abrams tanks attempting to enter the city limits. Jackson also eliminated resistance around the Ministry of Defence, clearing an LZ for troops to land and begin the ground assault. Vasquez was ordered by Command to head further into the city and extract a group of Marines. They managed to extract the Marines with the assistance of a Cobra, callsign "Deadly". Following the discovery of an armed nuclear device in the city center, Command recommended that Jackson's squad displace to a position outside of the effect radius. However, Deadly was shot down and Jackson's squad decided to go and rescue the pilot. They manage to retrieve her and headed back to the chopper. Just as they began leaving the city, however, the nuclear device was detonated, and Jackson's helicopter, along with all the other helicopters leaving the city, crashed. Everyone but Jackson was killed. He survived the crash, and upon regaining consciousness, slowly crawled out of the wreckage. After seeing either some of his squadmates slowly succumb to the effects of the nuclear radiation or their corpses, Jackson died a few moments later after seeing the aftermath of the explosion due to being exposed to the radiation from the nuclear explosion. The explosion left no survivors.
Sgt. Paul Jackson was one of 30,000 personnel who lost their lives under General Shepherd's command, which is revealed in Call of Duty: Modern Warfare 2. Their deaths are what fueled Shepherd's motives for revenge against Russia.
- In the earlier E3 2007 footage, Jackson was originally serving in the 1st Battalion 7th Marine Regiment prior to the unit being changed to 1st Force Recon.
- Jackson was originally meant to survive the nuke, as mission objectives have been found in the code to "Get radiation equipment", "Locate Commanding Officer", and "Find secure overhead cover".
