* Learn how to be a sounder.
(sounder uses sounds like footsteps/knife slashing etc.. to
detect the position of the enemy.)

* Learn how to walk silently
=walking while crouching will make no sounds by alternate
pressing the CTRL button while moving
=another option is by using Shift button while walking
but it will just walk you slowly.

* Learn how to use Silent Shooting
(Snipers)
=Scope and Shoot then immediately switch to your Knife or Secondary.
=you could use the F button to switch fast after shooting.

NOTE:
>Silent shooting can be heard by you always.
>If you perfect it even your teammates cant hear you shooting.

How would i know I'm doing it right.
>ask your teammates if they can hear your shoot while doing it.

Why should I Silent Shoot
>Silent shooting will make your enemy unaware that your shooting at them.
Thus making you aim better Headshot's.
