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.

He is seen in the mission "Crew Expendable" in Call of Duty 4: Modern Warfare guarding the ship deck along with Griffen, Captain John Price ,John "Soap" MacTavish and Gaz.

Wallcroft, along with Griffen reappears 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.
