During this mission you'll gain a new shotgun: the Dragon that shoots flaming grenades. It will be a great use in taking down enemies and should be your prime firearm throughout the mission.
You'll meet up with Reznov and he will give you documents about the enemy. Precede a head and snatch up a radio from your allied soldiers.
After making a call to military command, you'll have access to air strikes. Use this new function to call in air support that will destroy the enemy for you. You mainly want to target hard to hit enemies that are hiding inside buildings. The Communists will also let loose tanks that will require the use of the air strikes.
Follow Reznov and Woods some more and you'll be traveling through the upper levels of the building. An enemy tank will appear and will blast you down to the lower level. While here, place a bomb and destroy the machine gun nest. Your allies will finish of the tank and lead you to the escape point.
There is only so much room on the transport helicopter, and you'll let the wounded out first. Stay behind and provide ground support. Take cover in the building with Bowman to keep protect from enemy fire. You can still call in the attack helicopter, which you'll need to take out the tank to the east. After wards, run to the docks on the opposite side and climb on a boat to safety.
