Breifing
''In spite of the ceasefire, General Resource forces have commenced an attack against a Neucom air base. In order to maintain the ceasefire, clashes between them must be avoided at all costs. Defend the Neucom air base.''

Objectives
The mission's primary targets are four F-15S/MTs, mixed in with four F-16XAs. The player must destroy these fighters while defending the Neucom air base and their parked R-201s. Abyssal Dision and Keith Bryan are present, flying a F-22C Raptor II and a F-16XA, respectively, but cannot be targeted and will not interfere.

If the player destroys the four F-15S/MTs within 2 minutes and 59 seconds, a pair of B-1C Lancer IIs will spawn, with three F-16XAs as escorts. Shooting down the B-1Cs ends the mission and awards Mission Accomplished.

If the player destroys the four F-15S/MTs after 2 minutes and 59 seconds have passed, the mission ends and the player earns Mission Over, restricting them to a C Rank.

A Rank
An A Rank is obtained on this mission by destroying at least 11 enemies.

Debriefing
''The operation was a success. The clash between both forces has been avoided.''
