Iron Warriors

Iron Warriors are a bunch of Badass pricks who are robotic and torture,maim and burn down their old shit. A Chaos Legion specializing in breaking sieges (as in, taking a fortified location, though logically this should mean that they can do this and break out of a siege) which is shown in their love of artillery and greater focus on ranged combat, which stands in contrast to the other chaos space marine legions who are far more disposed to melee combat. They take no shit, but nobody at GW can decide on how they want to portray the Legion. Like we care what they think anyway! They also have a lot of Obliterators which are a bunch of muscle blobs armed to the teeth. Literally. Iron Warriors are also the batshit insane sickfucks behind Daemonculaba. They're the only Chaos Space Marines who don't break down in maniacal laughter constantly, as they see this as a sign of weakness. They're not terribly fond of Daemons like the Word Bearers or the Black Legion are, though they will make use of them unlike the Night Lords who don't even like Chaos and they aren't closet loyalists like the Alpha legion. Many of Black Library's authors are quite fond of them for being more "realistic" and "gritty" than the other traitor legions and they are one of the most frequently appearing Chaos Space Marine Legions.
