The suit itself is a highly modified Mark 7, with additional fixed armour plates on the torso that now enclose all of the suits cables, which were vulnerable to weapons fire, and a new armored collar protects the helmets respirator, and also addressed the vunerability issues of the neck joint, which had been know to act as a "shell-trap", (a round could hit the chest armour and deflect up into the neck joint). The new collar required a new helmet design, which caused problems for backward compatability with ealier earlier helmet types .

Mark 8 armor has only seen limited production thus far, and is seen in limited numbers on the battlefields of the 41st millennium. Often, it is worn by officers or squad leaders as a symbol of rank.
