Army ran the Zone Option RPO in the 2016 Spring Game.
The Quarterback throws the ball to the Wide Receiver unless the corner bails.
If the Corner bails, the Quarterback runs the two-way option versus #2.
This concept is another variation of the Triple Option; however, this variation involved a pass (versus the corner) and a run (versus #2).
The below-listed article shows you how the Zone Option RPO works.
