Rescuing your teammates
If a member of your team goes down, he will fall to the ground and will not be able to move or defend himself. When the first health meter is gone, that teammate will fall to the ground and a dark red health meter will take the place of the normal health meter. This health meter will slowly diminish. It is critical that you eliminate all hostiles around the downed teammate before you advance to try and save him. if you do not eliminate all the hostiles, another teammate might be taken down trying to save the first one. Be quick because the downed teammate will not last for long. Once it is safe, equip the medkit, stand over him, press R3, look at him, and press X. This will heal him and he will be back in action.

Spreading out munitions
Do not give too much of the powerful items such as tank mines, C4, anti-tank guns, etc. to a single person. If you have this person advance and he gets taken down by a tank, your other teammates might not have the firepower needed to even get close to the downed person, let alone heal him. It is always a good idea to have each teammate equipped with at the least one high powered explosive in case you need to take something out.

Weak spots on tanks
All tanks have very heavy front and side armor. However, the tank's rear is lightly armored. Smaller tanks can be hit with a rocket almost anywhere and will usually explode. However, larger tanks must be attacked with an explosive from behind. If you shoot it from the front or side, chances are you will not even make a dent.

Get a tank
