The Patrol - S1-E8
Corrected entry: During the "prisoner snatch" patrol, as the American soldiers are preparing to cross the river with the German prisoners, a firefight ensues. Immediately after Lt. Jones picks up the whistle off the ground, someone is heard yelling, "Go!" and a bit more which I was unable to understand. It sounds a lot like Tom Hanks, whose voice is quite distinguishable. None of the other soldiers on that particular patrol had that voice.
Correction: I looked at the scene and while it does sound very much like Tom Hanks there is no way to know conclusively this is Tom Hanks. The reason I think it sounds familiar is the actor that says Go is none other than Tom Hanks' son Colin Hanks, who sounds somewhat similar to his father.
