Red Alert Walkthrough: Allied 14
Tanya and 2 thiefs
Start by moving the three of them immediately south. An enemy will blow up the barrels to the north. After this occurs, move them all back to the north, far enough to be away from the southerly barrels, but no farther or a tesla coil will get them. Have Tanya slowly kill everything she sees, being careful to remain out of range. Move them all west across the board staying no further north than you started and clearing to the southerly end of the screen. Go west until you come to a land bridge, do no cross it. Make sure to keep the thieves a safe distance behind and watch out for enemies hiding in trees.
Once you've reached the land bridge, move Tanya north and have her start blowing up a few power plants. She will also have to destroy the cargo truck that's hanging around there by shooting it before reinforcements arrive. Use the barrels to the west when a helicopter full of enemies shows up. The barrels do a pretty good job of thinning them out if you time it right. You will get reinforcements from the north-east when the truck has been destroyed. After you've taken the power plants, you can start moving tanya and the thieves back east across the center of the base. Watch out for the flame towers... The thieves can each take a silo and get you some quick, easy cash. After the thieves are in, start blowing up flame towers and tesla coils. The mobile artillery works best because it can stay out of range. If you blow up too many defenses, all the buildings in the section will be sold and a bunch of infantry will need to be handled.
The best base location seems to be the one that you've just cleared. Since this is the final mission, try it from here!!
