Star Wars: Battlefront II/Changing of the Guard

Proceed southwest to the Main Entrance of the Cloning Facility and use Boba Fett to gain entry
It may be worded fancily, but all you're doing for this is walking a few yards to the entrance of the facility. On the way there, be sure to take out the top-mounted turret while it's still dormant.

Use Boba Fett to destroy the panel and gain access to the facility
Again, objective is longer than it needs to be... just blow up the panel, and the doors will open.

Retrieve a sample of clone DNA to ensure that the Kaminoans can never again clone themselves an army
Dispatch any troopers that approach, then go inside the facility. You'll face some more troopers here, but they shouldn't be a problem for your one-shot-kill rifle. Proceed until you get to the DNA sample and pick it up. Now, getting out of here is more problematic. A lot more enemy troopers will start spawning, and since you can't fly while carrying something, you'll have to do a lot of dodging enemy fire. Don't go around picking fights; and even if you die, you get a chance to use Fett again later on, so don't worry about it too much. You need to get to the Lambda-class Shuttle waiting at the top Command Post to satisfy this objective.

Take control of the Center Platform
You've probably lost Boba Fett by now, and that's okay. Spawn as a Stormtrooper and start blasting your way to the center Command Post. There are two main types of enemy clone troops; upgraded Jet Troopers that carry sniper rifles, and Rail Arc Troopers that carry the Clone Commanders' chainguns. The former should not be a problem if you don't charge in a straight line, but the latter is very powerful and should not be taken lightly.

The platform itself is not heavily defended; the only thing you should know about is the turret on the far side of it. Be sure to blow up the thing with grenades.

Destroy the Clone Life Support
This can be very difficult. You must destroy five Life Support mainframes in a very well-defended room... but the harder part is actually getting there. Even with Boba Fett (which you're given again with this objective), getting past dozens of respawning Rail Arc Troopers can be hard. Basically, avoid everyone unless they're right in front of you. If you fail with Boba, spawn as either an Imperial Officer or a Shock Trooper (only pick Stormtrooper if you've unlocked the Elite Assault Rifle) and keep going at it.



Once you're in the room, a bunch of Jet Troopers will spawn. Their guns are far from effective at close range, though, and come with a long reload time, so you should have plenty of time to blow up all five mainframes with the grenade or rocket launcher before dying.

Destroy the two Clone Gunships


Spawn as a Shock Trooper for this objective. The first Gunship flies around all over the map, shooting at you and your teammates with powerful cannons. However, it's a big target, so you should be able to take it down fairly quickly (besides, it only takes three rockets to destroy it). The second one is even easier; it just sits on a platform on the opposite side of the map from your Command Post and doesn't move. You could fight your way there, but if that's not your thing just stay at your Command Post and shoot a few rockets at it. The rockets travel far enough to hit it, so your mission will be complete anyway.
