Gather the rest of the team around you. After that, start moving towards the designated area. You shouldn't have any problems finding the right path. Be careful, though. One of the first groups of enemy soldiers is located nearby (#1). It would be best to lean out in order to get rid of the terrorists safely. You can also use the sniper rifle. You will have to be careful, because some of the enemies may actually try a direct approach. You will have to kill them with a machine gun (#2). You could also ask your teammates for help, although it's not necessary. You should be able to handle this problem on your own.
Start moving towards the larger street. I would recommend that you duck behind one of the parked cars. You should be able to take out a few soldiers from here (#1). You might also ask the rest of the team for help. Once all of the enemies are gone, head on to the opposite end of this road (#2). Once again, you must be very careful. It would be best to stick close to larger objects. You would be able to use them for cover (if needed).
You should be able to reach your destination without any major problems (#1). There aren't any new enemies in this area, however you must be very careful, because you might have missed someone. CHECKPOINT 2. Keep moving towards the large wall. Once you're there, turn left. I would recommend that you leave the rest of the team behind. Start moving forward (#2).
Now for the hard part. You will have to secure a large square. This is the most difficult part of the mission. The square is being occupied by A LOT of soldiers. I would recommend that you lean out CAREFULLY and take a closer look at your surroundings (#1). Remember to keep the rest of the team behind. Start using the tactical view in order to spot them (#2). You should also know that some of them will try to surprise you by making a frontal attack. You have to be ready for that!!
It would be best to use a sniper rifle during these fights... that is - if you have this weapon with you. Try and use the nearby wall for cover. Remember that you can't stay in the open for too long. Thankfully, you shouldn't have any problems with most of the enemies (#1). Like I've said before, a few of them will get closer (#2). Use the machine gun to take them out, although sometimes you won't have enough time to change the weapon. You could also move back and let the rest of the team handle this problem.
I would recommend that you use the tactical map frequently. Thanks to that, you won't be surprised by any of the remaining enemy soldiers. As I've said before, move back a little if that actually occurs (#1). The rest of the team will kill them without any problems. Before moving on any further, you will also have to take out all of the soldiers who were standing by the heavy machine guns. One of them is located on your left (#2). You should also leave at least 10-12 sniper bullets for later.
Once you've cleared out the whole square, gather the rest of the team around you and start moving towards the designated area. You should be able to notice an enemy vehicle in just a few seconds (#1). First of all, you will have to take out the gunner, mostly because your squad would have serious problems with him. Next, start shooting at the enemy soldiers. They will exit the vehicle (#2). Alternatively you could use the rocket launcher to destroy the humvee.
Keep moving towards the location where the first VIP has been kidnapped (#1). There aren't any new enemies nearby, however you should be extra careful (as always...). CHECKPOINT 3. There are a lot of paths leading to your destination. I'd recommend choosing the alley that's located in front of you (#2). Be careful. There may be some new terrorists here. You will have to kill them all before moving on any further.
You will have to reach the opposite end of this passageway. There's a small corridor here (#1). Head on to that location. Once again, I'd recommend that you leave the rest of the squad behind. Activate the tactical view. You should notice a lot of enemy units nearby. The terrorists are guarding the square with the presidential limousine. You will have to lean out carefully. Try taking out a few of them (#2). You may also use some of the carried grenades. Just make sure that you throw them properly. You'll have some problems with the guy that's standing by the heavy machine gun. Use the sniper rifle (aim at his head).
Once you've dealt with the visible enemy units, start moving towards the main square. You MUST be very careful. Keep using the tactical view (#1). It'll help to you pick a suitable route. Furthermore, you may notice additional units. There are some new enemy soldiers on your left (#2). You will have to take them out quickly. I wouldn't recommend sending the whole squad to kill them.
Make sure that the area is clear before you decide to proceed any further. Gather the rest of the team around you and start moving towards the presidential limousine (#1). Once you're there, the game will finish this part of the mission. You will be given a new task in just a moment. CHECKPOINT 4.
