Cover incurs penalties to hit something behind something else. This is a shield benefit which many do not know.
In ranged combat, breaking line of sight completely (such as total cover behind a boulder, wall, siege pavise, etcetera) will often help prevent you from getting hit. Even if the target's projectiles can get through your cover, firing blind gives them a capped Skill-9 to hit! One can still achieve line of sight with various types of super-vision, or having ultra-tech HUDs attached to drones or scanning devices.
Basic Set: Campaigns discusses penalties for varying degrees of coverage such as 50%, on page 407-408. Half coverage is a body part is a mere -2 to hit, but complete cover means it can never be hit. Doesn't really address other intervals. Presumably -1 for 25% and -3 for 75% covered? What about 99%? Advanced rules are needed!

- You certainly could sacrifice active defense by crouching behind your shield as cover, but that's at most going to buy you a -2 to be hit; skilled foes will just aim around it.

Old Rules[]
3e originally called these rules Cover and Concealment and described them on page 118 with helpful illustrations. These were much more thorough and included:

- -4 for head and shoulders (able to fire an arrow)
- -3 for half body
- -2 for light cover
- -4 for behind someone
- -4 for lying without cover
- -5 for lying with minimal cover ("head up", ties the -5 for first case)
- -7 for lying with minimum cover ("head down")
- -2 for crouching or kneeling
Sitting/Crawling are not addressed.
