Aim down your sights – Firing from the hip makes gives you terrible accuracy, which even though you are blindly shooting through a wall, still matters. You have to remember that the goal here isn’t just to have the bullet hit the wall, but go through and hit someone on the other side of the wall. Aiming down the your sights is also very important so that the bullet hits the wall at a 90 degree angle, which brings us to our next tip.

Shoot the wall at a 90° angle – As we have previously explained on this site calculating the damage a bullet does after going through a wall in Call of Duty 4 can be a complex process. One simple applicable fact is that bullets entering a wall straight on will do more damage than bullets entering a wall at an angle. This means that for max damage bullet damage you should move along a wall firing down your sights straight ahead.

Use your UAV – This one should be obvious. Use your UAV to pinpoint the exact location of targets on the other side of the wall, at which point you should have no trouble getting a kill. If you can catch the map just after it refreshes you will have the best chance, otherwise the target may have moved.

Aim at crouched level – Aiming at the level where in enemies body would be crouching gives you the best chance of a kill. This is because it is also the center of mass of standing Call of Duty players. You won’t be able to hit players that are prone, but if aiming that low means you would only have the feet of standing or crouching players to hit.
