Mission #4: Diamond in the Rough
This is the first time you can bring along a squadmate, so use him wisely. You'll find DiMarco's olympian near Nav Alpha, but she won't respond unless you come within 200 meters or so of her. Use the time it takes to reach Nav Alpha to secure the area around the olympian to search and destroy any Imperial opposition before contacting DiMarco. The olympian is maddeningly slow and will take its sweet time getting to Nav Bravo. Once there, call for the dropship, and the mission is over.

Opposition can get a bit heavy with roving patrols, which will include minotaurs, talons, a paladin tank, and a basilisk - expect some missile opposition as well, so if you haven't already, bring along some ECM equipment.

 
  Light up the turrets with your LTADS at the very edge of your radar range.
   

Mission #5: Operation Jailbreak
Be sure to bring along the second squadmate and the newly fixed olympian - you'll need it. You'll also need the LTADS to spot for the artillery boys. Head to the ridge and stop as the two closest missile turrets come in range. Target the one on the right (located visually in front of the tall communications tower) and summon the artillery to take it out. Remember that the tower must be targeted by you with the LTADS until it is destroyed, or you decide to change targets. Then, select the communications tower and hit it with the artillery.

As you start using the artillery, two minotaurs will attack from the rear - be sure to help out your squadmates on the minotaurs if they are having trouble, and they might. Then, use the artillery on the remaining turrets, but be aware of the rest of the base garrison, which is rather formidable. You may have to take out the communications tower yourself. Some of the garrison may attempt to destroy the hangars as well, which you must prevent at all costs.
