Command & Conquer: Red Alert 3

NOTE: I did this on Medium, if you're doing it on hard i'd suggest being alittle bit smarter with your units, my technique is normally "build enough of them and throw them at the enemy and im bound to win" in campaign.

The first part of this mission you only have terror drones. This part is easy, just double click (attack move) near the green objective and the terror drones will do their job. Your co-commander should take out the others while you take out the one on the left. Once that part is done you recieve tesla tanks, kirov airships and twinblades. This is enough to destroy the base. What i did was just double click (attack move) inside the base and all my units just stormed the base to death. The remaining terror drones should work off alot of the troops except the turrets, and the kirovs should own everything.

After you've completed the first step of the mission and be given access to build a base, make sure to work mainly on anti-air and anti-sea to start with, since they send paratroopers and aircraft carriers alot. Once you have these covered, watch to see when their chronoshift device (the super weapon that lets them transport troops) is ready to fire and check the back of your base when you hear it fire, because they will always fire it there. Train 5 hammer tanks and 3 terror drones, and make them control group 1. This will be your quick response team for any attacks at the back of your base.

Build an air field and several twinblades, 5 flak troopers and a sputnik. Using the forces left on the first island you were on, clear the enemy forces now gathered at the bonus objective (the bank) and ship your 5 flak troopers and sputnik over. Deploy the sputnik near the two refinery positions and position the flak troopers between the allied base and sputnik. Ship an engineer over there to capture the bank when all the enemy forces are gone, and the only enemies that will attack this position now are anti-air.

Once your base is securely secured (lol) train Natasha and swim her to the back of allies base, near the 4 refinerys there. She should take some damage going past but if you put her right in the corner she cant be touched. Use her to destroy all 4 refinerys and ore collectors, and the command hub there, and by the end she should be a veteran. From here, you can swim her foward and destroy the two turrets, and then the statue of liberty. This saves you charging through the entire american base to destroy it.

For the bonus objective to kill Tanya, she came and attacked me and i killed her then, i dont know if she will do the same for you. If she does, congratulations, if she does not, just build like 10 twinblades, fly over to where it says she is, and then drop an orbital probe on her if the twinblades cant kill her.

(PS: I also used the orbital probe drop special protocol along with the magnetic suck one to gather up about 20 tanks and drop them on their super weapons on the right hand side of the statue of liberty to end the problem once and for all.
