Changes

After the resurrection of Guilliman in late [[M41]], he began to see many of the flaws that came from overly-strict adherence to the Codex Astartes. As a result, he has reformed much of the Codex and eliminated much of its restrictions on Space Marines. New additions include the addition of [[Primaris Space Marine]] formations such as [[Intercessor]], [[Aggressor]], [[Inceptor]], and [[Reiver]] Squads, as well as the inclusion of two [[Space Marine Lieutenant]]s below the Company Captain, each commanding a demi-Company. Furthermore, Squads in the Codex Astartes are now defined as '''[[Battleline Squad]]s''' ([[Tactical Squad|Tactical]] or [[Intercessor]]), '''[[Close Support Squad|Close Support]]''' ([[Assault Squad|Assault]], [[Reiver]], and [[Inceptor]]), or '''[[Fire Support Squad|Fire Support]]''' ([[Devastator]], [[Aggressor]], [[Eradicator Squad|Eradicator]]s{{Fn|19}}, or [[Hellblaster]]). These formations exist alongside [[Space Marine Veteran|Veteran]] Squads, [[Scout]] Squads, and [[Vanguard Space Marine]] Squads.{{Fn|15}}
