2) Cover Bravo team
Now you will have to (QUICKLY!!) reach one of the northern buildings. It's being taken over by the Bravo team and you would have to assist them from the outside (#1). As a result, start running towards your new destination. Go north and then north-east (#2). Make sure that your squad is following you, because you won't have much time to prepare for an assault.
Your objective for this part of the mission will be to defend the eastern section of the building (#1), because all enemy soldiers will be coming from that direction. Before we'll take care of that problem, you will have to kill all enemy units (#2). Most of the rebel soldier will be standing in front of you, however one of these units may be hiding to your right.
This is a very similar fight to the church mission, so you'll have to make sure that your men aren't standing too close to each other (#1). You could also order one of your squad members to use a nearby heavy machine gun post (#2), however this won't be necessary and your colleague would be exposed to enemy fire. It's best that your team uses brick walls for cover.
As you've probably noticed, there are two roads to the east and enemy soldiers will be using these to get to your location (#1). I'd strongly recommend that you change your positions frequently, so you'll assist your men where it's needed the most. The northern route is going to be occupied by larger forces, so you must cover that area in the first place (#2).
You will also have to watch out for single rebel units, because they may actually get closer to you and your men (#1). You must kill these guys as soon as possible, because they will pose a serious threat to your safety. You could also consider using a grenade launcher (#2) which should be attached to your default weapon. You will have to aim the launcher at larger groups of enemy units.
Keep firing at the enemy soldiers. The next part of this battle will require you to defend the lower road, because that's where most of the rebel units will appear (#1). Make sure that you're using your tactical map to find them. You will have to defend this area until you've received a new radio transmission from your commanding officer (#2).
2a) Link up with allied reinforcements (This isn't going to be a difficult task, mostly because it'll only prepare you for the final challenge of this mission.)
Obviously I wouldn't recommend running towards the allied zone right away (#1), because the area is not safe. Allow your men to stay here a little while longer, so they'll be able to deal with the remaining rebel units. More rebel soldiers will arrive from the east, so you should find a good cover and kill them (#2). Turn around, so you will be looking at the western road. Wait for the second group to arrive.
You shouldn't have any problems spotting these units. I think it's fairly obvious that you need to attack them (#1) before they manage to find good cover. Otherwise you wouldn't be able to surprise them. Once they're gone, start moving west. It would be a good idea to stay close to the buildings on your left (#2).
