Once you disembark, if you head up the right side of the hill you can see an enemy by a tree up a little ways. Run up to him and try stab him with a knife. If you manage to get a stealth kill on him, you'll collect his Dog Tags and get a chievo/trophy.
Otherwise, slowly make your way up this hill. Make sure you stay in cover and at this point you can let your squad do most/all of the work. I found the left side fared better than the right at this point. Make your way to the top of the hill and inspect the body at the waypoint. Keep moving to the top of the hill to meet up with the rest of the convoy.
Now that you've climbed up, it's time to head down the other side. Head over to the left side as you descend and you should be able to find a well elevated position to take out the enemies in the field beyond. Make sure that everything up to the field is cleared because you'll have to make your way down to that field to stop the enemies from coming. Head down to the wall of the field and slowly make your way across. You can let your squad deal with most enemies. Just deal with whichever enemies you need to so that you can ensure that you make it safely to your next cover position. I found that after I made it down the hill, I moved right along the wall, and then diagonally left across the field.
You'll regroup with your squad and then have to make a counter attack. Attack the enemies in the next field and destroy the enemy vehicles with your SHAW. It takes two hits each. After you've killed the enemies and destroyed the tanks then you will run with your squad across the field. Just follow the squad and when they start heading left, go with them. Don't kill the jeep that pulls up in front of you, it's friendly. Take cover behind the walls here and start killing the enemies across the street.
Make your way further up the street while staying in cover. Wait for the tower to fall in the background and for the APC to pull up. Make your way over to the APC and use it for cover. Then move over to the wall across the street and use that as a staging area to clear the rest of the area.
Head back across the street to where you started and down the hill. You'll meet some resistance down below. Cross the dry river bed and meet up with your squad at the wall. Clear some space and move over the wall to the right to the two giant white cylinders. Use this for cover to clear more enemies. Eventually you will be able to move up and use a flatbed for cover. Kill the enemies in the lower field and try and make your way (safely) to the white cylinders on the right side of the lower field. Your squad will move up and get rid of any resistance.
Soon you will be notified of enemy armor. Head up to the roadside and you will see a good sized rock by a telephone pole. Go up on that and use it for cover while you use the SHAW to destroy the tanks. Be careful not to blow yourself up though because the SHAW has a larger blast radius than you think. Move across the street to a wall and get rid of the enemies by the bridge further ahead. Regroup with your squad once the enemy is gone...
Yes, he saw you.
Follow your squad and do as they do. You want to take cover so that you have something between you and the jet when he passes by. You won't be able to climb into anything but you want to keep something in between you from the direction he is coming. Slowly follow your squad to the bridge and take cover behind the destroyed cars. Keep heading up the bridge and eventually you'll have to grab the Stingers. These will be behind (not in) the destroyed jeep on the ground. Grab the Stinger and use it to shoot the jet down. Just wait for the solid tone and fire.
