Start the China mission and complete the first objective for $30,000. After you have successfully completed the objective, quit and reload the mission for another $30,000. You may have to walk back down the mountain for the money to be given to you. This can be redone as many times as desired.

Throw a grenade in front of your enemy to knock him down. Before he gets back up, either shoot him until he is dead or have the grenade launcher as your frontmount and use one of them to take him out. Depending on the area you are out will change the difficulty of doing this. Remember to use the aggro system to your advantage.

Pause game play and select the "Objective" option to check many briefcases you have collected for the current level. Note: You do not have to collect all briefcase in your first playthrough. You can find missed briefcases during subsequent playthroughs.

Just before meeting Ali Youseff you will see metal platforms with armed guards. Kill all of the guards then climb up the steps to the platform's second level. Climb another ladder to the third level to find the briefcase.

Go to the third floor of the SSC Tower. Instead of operating the lift, run to the far end of the third floor to find the briefcase.

You'll learn from training camp that defeating heavily armored targets require flanking and back-shooting. But what if your partner is pinned, carrying a hostage or regenerating? Simply knock the armored guy down using grenade launchers (barrel upgrade), grenades or some solid firepower. Most of the time, the guy will just roll over, exposing his vulnerable back. Then, move in for the kill.
