SImple macro that makes you crouch and stand in the timed durations for the purpose of raising your camo skill. If you speced your character before you realized how important this skill is this is for you. It is super easy to use. Crouch in a bush and press the assigned key on your keyboard (I paid programs I the up arrow). Your player will start standing and crouching roughly every 8 seconds. This is timed so you get the initial EXP bonus rinse and repeat. Enjoy.
