Heavy Gunners have a base armor of 500. At level 108 a Heavy Gunner would have approximately 8406 armor. Shattering Impact reduces the 500 base armor by six, for a total base armor of 494. A level 108 Heavy Gunner would then have approximately 8305 armor.

Basically Shattering Impact reduces total armor by six multiplied by the same factor used to calculate total armor from the base value. Kinda confusing but it's helpful.
