Forum:KB:Stormtrooper armor spear throw quote?

So I recall reading some time ago, that there was an instance of Stormtrooper armor withstanding a spear throw, thrown by a mechanical arm? Does anyone know what book that is from?

Or is it not an actual thing? I swear I remember there being something about it, but I'm not entirely sure...208.163.215.87 22:03, May 7, 2015 (UTC)
