Please help to explain term Hits break x% increased armour

I find this term is diffcult to understand, can someone please help, for example: Hits break 50% increased armour. Does that mean every of my hit will break 50% more armour?

yes, it will

e.g. if you should break 100 armour per hit, then if you get "break 50% increased armour" you'll break 100*1.5 = 150 armour, get 100% increased and 50 more from support: 100*2(increassed)*1.5(support) = 300 armour broken
