This mission won't begin with an introductory movie, however you will have some time to take grip of the current situation. Notice that you're on a moving train and you're currently inside the tunnel (screen). The most important thing for you to remember about is that you WON'T be allowed to jump off the train, because you'll lose. The only exception will be when you'll reach the train station, but don't ignore this information for now.
As you've probably noticed, there are some powerful turrets on the train and obviously you will have to use them to your advantage. I would recommend that you use a heavy cannon (screen). It's located far away from the container, but it's extremely powerful. You could also consider using two miniguns, however they have a limited field of view, so you'd have to switch between them often.
You can eliminate your first targets while you're still inside the tunnel. Wait for the train to start turning left and you should be able to spot a few guards on top of other carriages (screen). Wait for the train to leave the tunnel and get ready to engage a lot of Korean soldiers.
The next phase of this mission is going to be very similar to the chase sequence from the second level of the campaign. The only difference is that you can't stop here, so you'll have to be ready to engage new units at any time. Notice that your cannon has an unlimited supply of ammunition, however you must prevent it from overheating. The first set of buildings is located to your left. Remember to aim for explosive barrels (screen), gas canisters and cisterns.
There's a series of very challenging battles ahead of you and it's going to be important to disable enemy units or soldiers quickly. Focus most of your attention on destroying enemy vehicles. You'll also encounter an enemy gunship (screen). Use the fact that your cannon can turn in all directions to take down the helicopter.
You can't fight the helicopter for too long, because other any enemy units will reveal their positions in the meantime. You should know that you'll also have to take down two other gunships in the near future. Other than that, watch out for Korean armored vehicles (screen). They can injure you quite easily, especially since they usually stay close to the train.
You'll also be dealing with enemy machine gun posts from time to time (screen). They don't pose a serious threat, as long as you destroy them from a safe distance. Keep defending yourself until you've reached a small train station. Start off by listening to a radio transmission. You should also notice that an allied VTOL has appeared in the area. It'll help you in getting rid of enemy soldiers.
