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. To 
take out the tanks with the satellite dish on top, shoot the satellite dish with a 
sniper rifle and the tank will explode.


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. Once the 
alarm has been raised, an infinite number of enemies will start originating from 
certain points in the level such as barracks, campsites, or sometimes level 
boundary lines. The only way to stop this flow of enemies is to find the point at 
which they are appearing from and "secure" it. In other words, you have to kill all 
the enemies in the area (or building) and remain there for a minute or two to 
make sure no more show up. This way, you can systematically shut down the 
enemy's "points of origin", then complete the level even after the alarm has been 
raised.
