The military corps' headquarters made a decision to use the Mercenary USEAN Allied Forces 37th Air Force 18th Fighter Wing 1st Special Tactical Fighter Squadron "Scarface". which consisted Scarface One and some other pilots. They were given the job of suppressing the coup d'état that broke out in the military when the country's leaders had to leave for diplomatic reasons. Scarface One received all-out support from the military corps, full cooperation through their intelligence division and military supplies. He, along with his squadron, had completed many battles against the coup d'état, including the destruction of a submarine launching cruise missiles. He had also fought as a mercenary before against another coup d'état, in the small Republic of Kaluga, where he had also saved that country from the coup d'état.

- Contrary to popular belief, Scarface One is, indeed, the first playable character to speak. However, he only speaks once during a landing.
- Scarface One is believed by some to be the same person as Phoenix One. However, this is still unconfirmed. If he is, this would make him the first character to appear in more than one game (Air Combat and Ace Combat 2).
- Scarface One, Falco One, William Bishop, Doug Robinson, SO Spense and Janice Rehl are, to date, the only player characters heard speaking. Other player characters like Cipher, Mobius 1, Blaze, Talisman and Gryphus 1 can't be heard speaking (though Gryphus 1 is quoted).
