Don't be in a big hurry to rush to the aid of Gamma Base. You have 30 minutes to prepare. Move a combat group to the pass leading north and have them hold there to take care of enemy units coming south. Build a Sensor Tower and a CB Tower on the ridge east of this area, along with lots of artillery emplacements.
Next, build up your VTOL force. You'll lose several VTOLs, so construct a second VTOL Factory and begin producing VTOLs with Cluster and Phosphor bombs. NEXUS will send VTOLs to attack your forces. Position several AA units just west of the pass to intercept them as they come over the mountains. Finally, construct a Repair Facility south of the pass to keep your units near the front.

When you have at least 12 VTOLs ready, send them on a Wild Weasel mission to take out the SAM sites northeast of the pass. They can cause a lot of trouble, especially if your VTOL base is just to the south. It will take a couple of attacks to destroy them all. Replace your lost VTOLs; then take out the SAMs northwest of the pass, and then the rocket launchers nearby. After you eliminate the final two SAM sites in the northeast, the skies will be fairly safe for your VTOLs.
When your VTOLs begin their first attack, you'll receive a message from NEXUS that Gamma Base has been absorbed. The mission timer will increase to 90 minutes. There's no hurry to rescue anybody. You need only wipe NEXUS from the map. With the SAMs eliminated, use your VTOLs to strike at the defensive structures northeast of the pass. Then send in a large group of combat units to mop up and recover an Artifact.
Now send your group to the western map edge to take out the outpost there. Again, use your VTOLs to soften up and destroy the defensive structures. Recover a second Artifact. This area may seem clear, but NEXUS transports will drop off additional units when you least expect it. Be ready for a fight.
All that remains is Gamma Base. Send in your VTOLs to destroy the AA emplacements, and then the defensive structures. Then advance your combat group to mop up. Don't destroy everything. You want to use the extra time at the end of the mission to prepare for the future. Recover the Artifact at Gamma Base and complete all of your research.
