Wallcroft

"Alright mates, let's do this."

- Wallcroft just before converging on the warehouses at the beginning of Mind the Gap.

Sergeant Wallcroft is an SAS soldier who serves alongside Soap, Price, and Gaz during the events of Call of Duty 4: Modern Warfare and Marcus Burns in Call of Duty: Modern Warfare 3.

Cargo Ship Mission
"Wallcroft's idea to switch to pistol vs. Reload-Pretty brilliant. Who knew Wallcroft could be good fast at anything?"

- Soap on Wallcroft in Soap's Journal.

He is seen in the mission "Crew Expendable" in ''Call of Duty 4: Modern Warfare. ''Wallcroft, Griffen and Gaz dropped down to the ship to retrieve a bomb headed to the Middle East after 'Soap' MacTavish and John Price cleared the first wave of Russian troops. Wallcroft and Griffen were ordered to cover Price's back while the rest went into the ship. Before Price and the others could retrieve the bomb, Baseplate reported a MiG airstrike on the way. Wallcroft and Griffen fled to the safety of the evac chopper. Price requested an update on their status, they reported that they were on the chopper but told the 4 to get out as the MiG's open fired. The 4 managed to escape the ship and the chopper brought the group back to London.

Downtown London Mission
Wallcroft and Griffen reappear in the Call of Duty: Modern Warfare 3 campaign mission, "Mind the Gap", as SAS squad leaders. After the SAS picked up a suspicious cargo, the contents were not yet known. Baseplate assigned Wallcroft, Griffen and Marcus Burns and other SAS to intercept a group of 5 trucks with one of the crates being the unknown cargo. Marcus, Griffen and Wallcroft intercepted a truck before it took off. It was not the truck with the cargo so Wallcroft, Griffen and Burns went into the subway where another cargo was suspected of holding the contents. After avoiding other trains and civilians whilst using a truck in the subway, the train crashed when a SAS soldier shot the train driver. Wallcroft and Burns survived but Griffen was killed in the crash. Wallcroft and Burns battled there way through enemies, eventually getting assistance from local police. Wallcroft and Burns meet up with other SAS and police who had blocked off another road where another truck was suspected to pass through. They were right and the large force of SAS open fired on the truck, killing the drivers. They secured the truck and tried to contact Baseplate to know where the other trucks were but received no answer. Unfortunately, another truck on the other side of town exploded, killing a family and exposing the public to a deadly chemical.
