Walkthrough
Wait for the cutscene to finish then walk forward and melee the enemy in front of you. Get up and go up the stairs to the right. When you are told to, headshot the person leaning over the balcony. Now go to the door marked breach, press use to breach. Everything goes into slow motion. Here, you can easily take out 4 enemies with 4 shots for an achievement. After breaching has finished, the slow-mo ends and normal combat begins. It should be a very easy fight. After the hostages have been released, go up the stairs, take note of a shelf to your left at the top of these stairs, this contains Intelligence.

Now go round and breach the other door, use the one closest to you as that one seems to have easier shots. After you have gone in, plant C4 on the bodies then retreat to near the scaffolding. There are many weapons near there, the AT4 Rocket launcher will help with the enemies if the C4 doesn't get them all. Continue onwards, keeping to cover (the pillar seems to be a good choice). There is some intelligence in a building to the right. Now go up the stairs, there will be an AT4 behind cover, swap it for your secondary weapon as a helicopter will appear, take it down then go back for your weapon.

Use your grenade launcher on the fuel tank in front of you, use where the AT4 was for cover as anywhere further on is fairly exposed. Kill all the enemies then continue on. It seems better to go through the building to the right as it provides more cover. Go through killing all of the enemies, but before you proceed to the top deck, go inside the building near the stairs, at the top of the stairwell there will be some guns and underneath it there will be the third piece of intelligence. Pick up some weapons with a thermal scope and go upstairs.

As you go up, the enemy will pop smoke making them hard to see. Go left, kill the enemies moving up and rush forward to the cover that they were going to use, kill some of the enemies on the upper balcony using the thermal scoped weapon and kill a few. After most of the enemies are dead, join your squad near the door. This is the final breach and it is harder than the others as there are explosives in the room. Shoot a few enemies then once you get shot at, get to cover behind the doorway and after you regain your health, go back for the final kill. Now follow your team to the Helicopters to complete the mission.

Intelligence (3)

 * After the first hostages, go up the flights of stairs, it will be to your left on a shelf.
 * In a storeroom, the next building to the right after the building where you plant the C4
 * Inside a building, there is intelligence behind the stairs going to the second floor (these stairs do not lead to the end of the campaign, there are weapons at the top).
