Command & Conquer: Generals - Zero Hour/China Nuke General vs. USA Superweapon General

The Nuke General has many strengths, but offensive air power is not one of them. Helixes work great for defense, but they are slow-moving and easily destroyed by the EMP Patriots deployed in this mission. It takes up to four MIGs upgraded with nuclear missiles to just take out a single EMP Patriot.

The best method for destroying the three Particle Cannons is by your weapon of mass destruction – the Nuclear Missile.

Do not build an air force on this mission, but simply forge your way straight into building a Nuclear Missile.

Walkthrough
The usual build routine needs to shaken up a bit for this mission.

Build a Reactor, extra bulldozer, Barracks, then two Gattling Cannons before building a Supply Center.

Immediately research Capture command and build a pair of Red Guard, setting the Rally Point by the two oil derricks. Capture the two oil derricks.

Wait for the A10 Missile Strike planes to blast away one of your Gattling Cannons, rebuild it, and then build your Supply Center. Build an extra Supply Truck.

Build up to four or five Gattling Cannons and then build straight through to your Nuclear Missile – War Factory, Propaganda Center, then Nuclear Missile.

If your Supply Center, War Factory or Propaganda Center are destroyed, don’t rebuild them until after your Nuclear Missile starts building. The destruction of any of these structures shouldn’t slow you down because you will go straight from building one structure to the next.

It will be two steps forward, one step back. You will constantly be replacing your structures -- Barracks, Reactors, Gattling Cannons -- and bulldozers. Just keep rebuilding them. You will be fine.

Build a few extra Gattling Cannons to protect your base from Ambushes and troops dropped off by Chinook helicopters. Overlords will be popular targets for the A10 Missile Strikes.

Destroy the first Particle Cannon with a combination of a level three Artillery Barrage and a Nuclear Missile.

Be absolutely sure to keep your Nuclear Missile repaired when it is attacked.

Build a second Nuclear Missile. Use both of your Nuclear Missiles to destroy the Command Center to stop the A10 Missile Strikes, which are more damaging than the Particle Cannons.

Destroy the final two Particle Cannons by any combination of weaponry you choose. Continue building additional Nuclear Missiles to speed up the destructive process.

If you wish, build an airfield and research the nuclear upgrade for your MIGs at the Nuclear Missile facility.

It is not necessary to destroy Fire Bases, Artillery Platforms and Patriots to complete the mission.

The only building necessary to destroy on the northwest island is the Supply Center.

The Particle Cannons and Command Center will not be rebuilt but the War Factory and Air Field will be. Destroy the two dozers to stop them from being rebuilt.

Mission accomplished!

Alternative
This strategy didn't work out well for me vs a hard opponent. I startet with gattling turrets, but as soon as I had my Warfactory completed, I started building gattling tanks. They do the same damage, are cheaper and you can concentrate your defence in one spot. Also, by constantly moving them around, you keep them from being hit by the A10s, who in my case frequently fired at their old location. For me, taking out the airfild also was a top priority. As said above, don't worry, you'll be fine as the attacks do get sparser over time.
