Prevent reinforcements:  If you have been found, equip a small weapon and shoot their codec so no reinforcements can be called.

Enemies run away:  If you have been spotted, also try taking out your biggest gun. At times, your enemies may get scared and run.

Defeating enemies:  When faced with a single enemy, quickly go for his/or her radio or arm.

Using pipes:  When you see a guard next to a pipe ( which may be hot) shoot where you want the steam to hit your enemy. If the steam hits his leg, he will start to limp. If the steam hits his arm, he will be unable to use his gun or weapon. If the steam hits his radio he will be unable to call for back up.

Attract and destroy enemies without being near them:  Attract enemies by stepping on things that make loud noises. They will investigate the noise. Note: Enemies have to be near your position to hear the noise. You can also knock on walls to lure enemies. Place C4 on the surface where the enemy will be coming from before he or she arrives. Hide, and when the enemy gets near the C4, blow it up.

I trust you all know how to get dog tags, but if you don't, then read this. When a guard has his back turned to you, go up to him with a hand-gun and press fire but keep it held. Then, when the guards arms fling up into the air, walk to his front with your gun still pointing at him. Aim the gun at his face to get a dog tag. If the guard says something like "who are you" or "just try to pull the trigger", then shoot him in the arm or leg with your Socom/USP.

All guards have dog tags on the difficulty levels very easy, easy, normal, hard and extreme except the guards who are called in for back-up.
