Enemies

Grunts:
Styled after Reachs variants, significantly better armed than in Halo 3 with more health and some get light shields

Grunt Minor - Same as vanilla, armed with plasma pistols

Brutes:
A mix gameplay wise between 2, 3, and Reachs versions. They have halo 2's berserking animation and are just as tanky along with halo 3's power armour. There helmets can be shot off like in reach and there power armour does not get destroyed after their shields get depleted.

Brute Captain minor/major/ultra - A lot stronger shields than the regular variety almost on par with elites. Berserk when their squad gets wiped out

Brute Bodyguards - Sporting black armour, they are the strongest of the regular brutes and can dual wield their weapons
Brute Chieftains - Both have greatly increased shields and health

Pretty similar to the ones found in Halo 2, better shields than brutes that can recharge but a lot less health and a lot more mobile

Elite minor/major/ultra - Plays just like halo 2s variants, ultras will berserk with energy swords
Elite Spec-ops - Same stats as the elite major, seen leading spec-ops grunts, some can cloak
Elite Field Marshal - Classic gold elite with energy swords and other heavy weapons, Very strong shields

Jackals:
Almost the same as halo 3s, slightly more health and carry stronger energy shields

Jackal ultra - have very strong white energy shields and more resistant to flinching when they get shot
