Our mission is the liberation of Griswall. I'll explain the details. Griswall is protected by the Atmos Ring powered Meson Cannon. Our troops will not be able to approach the city because of the MBSRs (Meson Beam Stabilizing Regulator), brought in from Monte Breeze. Our only hope is to send a small squadron of fighters in for a surprise attack, and take out the cannon. Fortunately, the enemy has put all of their faith in the cannon, and has yet to deploy ground troops. Destroy the Meson Cannon and the fighters protecting it, and the city is ours. The capitol's liberation is finally within our grasp. Sir, please decide the course of action.

The mission's main objective is to destroy all targets. There are several SAMs protecting the Meson cannons, and several fighters providing air support. In addition, reinforcements will arrive after several targets are destroyed.
