I think when I coded the unarmed damage on_hit-trigger I made it so that you can even knock out heavy(head) armoured guys given heavy gauntlets, enough strength and a shitload of hits. Iirc it basicly takes the raw(i.e. pre-armour) damage of a punch and does some custom calculation using helmet armour of the victim and gauntlet weight of the attacker, bypassing the native armour damage calc. The whole thing was meant to give the chamberblock-elite a way to skillztroll.
