Personal War

"With the fighting fast approaching Athens, Stavros has insisted that he be allowed to survey the damage in his own hometown in Greece.

You must escort Stavros through the town and to a nearby friendly outpost. Once you reach it, evacuate Stavros to safety.

If anything should happen, get Stavros to safety any way possible. He must be kept alive."

Personal War the fourth Allied mission in the expansion.

Background
Tanya and the Greek commander Nikos Stavros are parachuted next to a town which is under attack by Soviet ground forces. They then flee to a nearby Allied outpost with the Soviets in pursuit, where they would escape in a Chinook. However, Soviet MiGs will destroy a bridge leading to the Chinook, forcing Tanya and Stavros to evacuate to another extraction point much farther away. Two atomic bombs are then dropped on the outpost, with Soviet forces finishing off any survivors before going after Tanya and Stavros. The Allies will sell their structures and defenses after the second detonation, hastening their demise.

Tanya and Stavros will receive minimal reinforcements along the way to aid them in reaching their destination. There is also a Soviet base which lies between them and the Chinook. The mission is a success when Stavros enters the Chinook and is airlifted from the area. While Stavros is to be kept alive at all costs, Tanya is an exception.

Walkthrough
On Hard Mode, this mission has to be played pretty much flawlessly if you want to win it. Every step Tanya and Stavros make has to be done instantly and without hesitation, or the units chasing you will kill you before you get remotely close to the rescue helicopter.

As soon as Tanya and Stavros hit the ground, send them east and slaughter everything between your starting position and the Soviet troops in the small town. Immediately turn north, then run into the small passage in the hills to the west to avoid the Mammoth tank rampaging its way through the village. Continue to the north, and you will find a small Allied base. Approach it, but don't bother going into it - it will be swarming with Soviets soon, and then it's going to be blasted by a nuclear bomb.

Ignore the base and head south-west instead. Some infantry will be in your way, but the real threat is the pair of Mammoth tanks south of the explosive barrels. Use Tanya to blast the barrels, then collect the medium tanks that come off of the transport on the coast. Quickly use them to take out the western Mammoth and have Tanya and Stavros move south along the coast. There are quite a few Soviet troops hiding behind the trees, so keep your eyes peeled (leading with the tanks will help you find them). When you reach the bottom of the screen, look for the small crate - it will heal all of your units for you.

You'll receive some paratroopers to the west, but there's a Tesla Coil within range of their landing zone. As soon as they hit the ground, rush them down around the concrete and detonate the barrels by the power plant to take out the Tesla Coil. Immediately send all of your forces due west all the way to the edge of the screen, then follow the edge straight to the north. Use your tanks to detonate the barrels in the north-west corner of the Soviet base, then use them to take out the flame towers while Tanya and Stavros head for the safety of the clearing the barrel explosion created.

You'll receive reinforcements on the other side of the base, so use everything you've got to make a safe passage to the eastern side of the base for Tanya and Stavros. Get them to the upper-left corner of the map, then stick them in the Chinook to end the mission.

Behind the scenes

 * The mission was originally named Fall of Greece 1: Personal War in Counterstrike.
 * Given the events shown in mission briefings of the Allied campaign in the main game (Von Esling briefing the player on the collapse of the Greek front, and Stavros being visibly upset at the destruction of his homeland), it is likely that this mission, along with Evacuation, is intended to be set between the fourth and fifth missions, if this mission is indeed canon. However, it is not critical that Tanya survives, which is at odds with her appearances in later missions of the campaign.
 * A glitch allows the player to use the green helicopter instead of the blue one to evacuate Stavros, involving killing the civilians that run to the base. A video of this being done can be seen here: https://youtu.be/LhToAZOLy70.
