Skyside 6

Skyside 6 was the radio term for God used by U.S. ground forces during the Vietnam War. It was often used as a source of humor in situations where only God himself could provide the solution to a given set of circumstances.

A typical radio communiqué including this call sign might sound something like this: "Pied Piper 6, this is Alfa 6 Actual. Let me speak to your Actual. Over. Alfa 6 Actual, we're not gonna get out of this mess without the help of Skyside 6 Actual."
