We're back as Soap for this one. Look out the hole and start sniping some of the terrorists on the left. We need to weaken them up a little bit so that Shepherd's men can be more effective. Kill a few and then wait for the helicopters to make a run on the BTR. Move out of the aircraft body and stick to the left. We're heading for the next large airplane body. It's red and over to the left side. You can hide in here if you need cover, but it doesn't have an exit. We need to move past this and get up to the destroyed car. Kill a soldier who might be here.

There's a Hummer with a 50. Cal on top of it just past this point. Stay low, and then lean out to snipe the gunner. Move further along the left side. There will be a few soldiers back here behind the next broken airplane. Wait a moment to gather yourself, and then sprint forward and to the left again. You won't survive long if you try to get yourself involved in the battle. They just spawn too fast. You need to come to a stop on the left side of a shipping container. You'll be between the container and the fence and have a good sight on the Russian position in front of you.
Gun the guys on top of the pipes down. Clear a little path and then run through the hole in the container. Take cover by a red container again and wait a moment for a truck to take out that Humvee. Hang back just a little long while Shepherd's men launch an attack against the Russians with a helicopter.
