Private James Ramirez is a playable character and the protagonist of the United States campaign in Call of Duty: Modern Warfare 2 and Call of Duty: Modern Warfare 2 Campaign Remastered. Ramirez is introduced in the mission "Wolverines!", serving alongside Sergeant Foley and Corporal Dunn in the 1st Battalion 75th Ranger Regiment, Hunter Two-One, and is the second playable Ranger character in the game.
75th Ranger Regiment
After Joseph Allen was executed by Makarov in Russia during the airport massacre, Ramirez took over Allen’s place within Hunter Two-One. Ramirez and his squad respond to an unexpected Russian invasion and move to Virginia. They then help friendly troops extract "Raptor", a High Value Individual, and then go on to Arcadia to rescue trapped civilians with the help of the Stryker armored vehicle codenamed "Honey Badger".
After destroying AA batteries threatening the civilian's evacuation transport, the Rangers move to a devastated Washington D.C. where U.S. troops are fighting a desperate battle against Russian troops to defend the capital. Hunter Two-One assaults and attempts to clear the Department of Commerce building, eliminating a 'crows nest' of Javelin Missiles and an M82 which they turn against the invaders, buying the evac site valuable time. They board a UH-60 Blackhawk and assault Russian ground forces, only to get shot down by SAM missiles over the Department of Justice building. After their helicopter crashes, Ramirez finds himself trapped in the Blackhawk with injuries and the squad is swarmed by Russian forces. As they run out of ammo, Pvt. Wade is killed while handing Ramirez an M4A1, Dunn is wounded, and several squads of enemy soldiers assault their position while a nearby Havoc blinds the surviving Rangers with it's searchlight.
All hope seems lost until an ICBM launched by Captain Price Explodes over the east coast of the US. The resulting EMP knocks the enemy Havoc and other aircraft, Russian and American out of the sky. The Rangers help Ramirez out of the helicopter and retreat with his squad into a nearby building while aircraft disabled from the EMP fall from the sky. After encountering a friendly runner, Pvt. Vaughan, who tells them to get to Whiskey Hotel, they fight their way through some office buildings. Despite heavy resistance from the Russians, they eventually regroup on the White House Lawn, where U.S. stragglers under the command of Colonel Marshall are attempting to retake Whiskey Hotel (The White House). Marshall orders the squad to proceed up the left and they fight through extremely heavy Russian resistance. After fighting through the desperate Russian troops, Ramirez and another Ranger take point and make their way to the roof. They wave green signal flares to call off the friendly airstrikes that are part of the "Hammerdown Protocol." He then sees other green flares on other buildings across the ruined Washington D.C..

- Due to Ramirez being given orders so frequently (a total of 56 scripted times during the campaign, usually given by Sgt. Foley), this has created a meme among players entitled "RAMIREZ! DO EVERYTHING!" which usually features a poster of Sgt. Foley giving impossible or absurd orders.
- Ramirez has one of the fastest Pit completion times at 28.7 seconds.
- In Call of Duty: Modern Warfare 2 Campaign Remastered, Ramirez can be seen with the Predator in the mission "Wolverines!".
