The Mk.X has a number of different variants, such as the '''Mk.X "Gravis"''' heavy armour used by Commanders, [[Aggressor Squad]]s, [[Eradicator Squad]]s{{Fn|40b40}}, and the [[Jump Pack]]-capable variant used by [[Inceptor Squads]]. The Gravis pattern of Mk.X Armour is more heavily protected and allows for a level of protection near [[Terminator Armour]] level but with the flexibility of standard designs. A lighter [[Jump Pack]] and [[Grav chute]]-equipped variant of the Gravis Pattern, known as the '''Omnis-Pattern''', is utilized by [[Vanguard Suppressor]] Squads.{{Fn|40a40}}
