at the beginning where you go to secure hostage, you need to use pistol with silencer to take out the enemy without alert the alarm, the first 2 enemy has to be taken out together with your partner

after that you need to watch out for CCTV at the ceiling corner, you need to shot it with your pistol

after secure hostage and escort the humvee, each of you need to take 1 lane and clear your own lane, same goes to the ambush part

after the ambush, you need to use C4 to detonate the gate, only your partner or you need to go down and set the charge, while the other stay at the humvee to provide fire support (enemy will come from the right flank of the humvee after detonate the charge)

the last part where your humvee exploded, stay inside the small shop lot and slowly clear out the enemy and wait until the chopper come
