 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.
 
 
 
 Last resort attack on tanks
 If you need to take out a tank but have no more long range rockets, 
 it is possible to get close to it without getting hit. First, you 
 will need to have a sniper rifle to zoom in on the top of the tank 
 to take out the gunner, if there is one. After he is down, throw 
 a smoke bomb in the direction of the tank. Try to get the smoke 
 bomb in as close to it as possible. While the smoke is in the air, 
 you can run up to the tank without being hit. The smoke will make 
 it impossible for the tank to see you. Get directly next to the 
 tank and plant a C4 next to it. After it is planted, throw another 
 smoke bomb slightly further away from the tank. Make a mad dash 
 for the smoke. If you are fast enough, you will get behind the wall 
 of smoke and can then make your way to safety. Then, detonate the 
 C4. If you have C4 with a detonator, run to the tank, crouch, plant 
 the C4, then quickly run away. When you get about 10 feet away, 
 use the detonator to explode the C4.
 
 
 Last resort attack on SCUDs
 SCUDs can be blown up with the sniper rifle if they are in the launch 
 position. Shoot the rocket a few times with it.
 
 
 Charge the enemy
 The game sends an infinite amount of troops after the alarm has 
 been set. The best way to defend yourself is to charge ahead as 
 fast, but also as safely, as possible. In some levels you can cut 
 down the number of men by almost fifty. If you are low on ammunition, 
 health, etc., this is a good way to cut down on the amount of men 
 you have to deal with. It also works sometimes if you send a man 
 far ahead and hold him there, then do your objectives for your mission.
 
 Easy way to kill tanks and special weapon abilities
 To kill tanks easily all you have to do is shoot at the wheels and you can practice 
 this on one player training which also tells you that the gun that Bradley starts 
 with can be used as a grenade gun by holding triangle going onto his original gun 
 and pressing R1.
