Call of Duty 4: Modern Warfare differs from previous installments of the Call of Duty series. Previous Call of Duty games have a distinct three country-specific campaign style, while Call of Duty 4 has a more film-like plot with interlaced story lines from the perspectives of Sgt. Paul Jackson of the Marines 1st Force Recon and Sgt. 'Soap' MacTavish of the British 22nd SAS Regiment.
