Sons of Horus MK lll Tactical Legionary
Sons of Horus Legionaries in Mark III "Iron" power armor formed the backbone of the XVI Legion's battle line. This armor pattern, developed for boarding actions and close-quarters combat during the Great Crusade, proved ideal for the brutal warfare of the Horus Heresy. The sea-green of the XVI Legion marks this warrior as one of the Warmaster's own, a veteran of countless campaigns.
