In the mission "Dam Approach", though it is not specified which helicopter carries him, Cowboy has several speaking parts. His team separates from Noyce's team at the beginning of the mission to engage half tracks on their way to Hoover Dam. He then appears at the end of the mission to assist the player in the final areas of the mission.
He makes a brief appearance in the mission "Lights Out" where he drops Hughes, Cole and Noyce near the interior of the dam.
