Changes

The Iron Warriors were organised as a number of Grand Companies each commanded by a Warsmith. Originally each Grand Company would have had a similar organisation, totalling around 1,000 Space Marines. At the time of the Heresy, the Legion had at least twelve Companies, although with the widespread deployment of many small detachments of the Legion at the time it is impossible to be sure if this figure of around 12,000 fighting [[Astartes]] was their maximum strength.¹
