Marlowe's convoy was a group of vehicles set out to find the Atlantis of the Sands.
After Katherine Marlowe and her hermetic order had captured Victor Sullivan, who knew the coordinates of Iram, they set out into the Rub' al Khali in a large convoy. They planned to send a Cargo Plane to airdrop supplies to them. Meanwhile, Nathan Drake, who had escaped from Rameses' pirates, stumbled into Elena Fisher's apartment, and after planning, the two drove to the airfield where the cargo plane was being loaded up. While Elena stayed behind, Nate managed to jump onto the landing gear from a jeep. After a fight on the plane some hours later, the plane was damaged and had crashed into the desert, with Drake surviving by deploying the parachute on a supply crate. After being rescued by Salim and the Bedouins, they've set out to intercept the convoy.
The convoy in whole consisted of around twenty heavy, reinforced trucks with guards riding in each of them. Also, there were around ten motorbikes and around five turret jeeps. Most of the trucks carried supply crates and some had mounted turrets. The captured Sullivan was transported in one of the leading jeeps. Neither Marlowe or Talbot were present in the convoy, but were present in the Atlantis of the Sands.
