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.

SAS Career
"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 guarding the ship deck along with Griffen, Captain John Price, 'Soap' MacTavish, and Gaz.

Wallcroft and Griffen reappear in the Modern Warfare 3 campaign mission, "Mind the Gap", as SAS squad leaders. Wallcroft acts as the operation leader, and is tasked with capturing trucks that appear to be loaded with an unknown cargo (which are in fact, chemical agents). He successfully clears the docks, the nearby warehouse, and secures one of the trucks that turns out to be a decoy. He is then forced to chase a hijacked metro car in a truck. Along the way, their truck is destroyed and Griffen is killed in the process, but Wallcroft, along with Burns, clear the subway station infested with the remaining terrorists, and support joining SAS units in ambushing one of the suspected trucks.
