I've been wondering, is that a particular reason why ranged weapons vary from AP1, AP2, AP3, AP4, AP5, AP6, AP-, and no AP, while close combat attacks are either AP2 (power weapons/monstrous creatures) or have no AP (or in a very few cases, AP1, like Lysander)? I find it hard to believe that the chainsword carried by a Khorne Berserker has the same armor penetration as whatever sad excuse for combat weapons Tau Fire Warriors have.

In Fantasy, this is made up for my the mechanic where strength reduces your armor save, but does anyone have any insight to why this is?
