Viper 5 is a minor character in the Ace Combat series, though he has appeared in AC04 & AC5.

Ace Combat 04
In AC04, he is a pilot for the Independant States Allied Forces. He is adressed many times over the radio and flew with Mobius One many times as well. His flown plane is unknown, because during the course of the game, friendly aircraft will change.

Ace Combat 5
Six years later, in AC5, he was a pilot for the OADF. He is only noticed in mission 16, when someone adresses him as Viper 5. His role in the battle or his piloted plane was unknown as well.
