Raider iconoclast armor is a variant of the raider armor added to Fallout 3 with the add-onThe Pitt. Its appearance is that of a worn-out radiation suit or mining suit, armored with several patches and a shoulder strap. It also has a hammer and two picks on the left leg.
An iconoclast is a person who is devoted to the destruction of religious symbols, or, by extension, established dogma or conventions. This term would fit well with the sadistic way raiders deface monuments with corpses and gore.
