UNSC Marine Corps

"Man, I'm never going to get another hour's sleep."

- Corporal Locklear

"Sleep when you're dead, Marine."

- Staff Sergeant Avery Johnson

The UNSC Marine Corps is the standard infantry of the United Nations Space Command Defence Force.

A rugged and diverse assortment of warriors, the Marines of the UNSC are fighting a losing war against the Covenant's superior weaponry and numbers. Under the leadership of notable figures such as Captain Keyes, or Admiral Whitcomb, they continue to wage a furious struggle against the Covenant, even as their numbers dwindle. They're the best of the best. Unfortunately, they're only Human.

Summary
Marines have few bio-augmentations and usually wear passive camouflage uniforms. They wear dark-colored metal-alloy armor to shield them from plasma fire and the few occasional bullets. Marine helmets are mounted with display eyepieces and helmet recorders, which give them information about their surroundings. As well as helmets, Marines on field ops in more humid locales sometimes choose to wear boonie covers. Orbital Drop Shock Troopers, distinctive in their black-based camoflage scheme and more protective body armor, are a special operations group within the UNSC Marines.

Marine NCOs are easily recognized by the eight-point covers carrying the Eagle, Globe and Anchor of the Marine Corps that they wear. They occasionally wear helmets, although in Halo: Combat Evolved, they are portrayed as never wearing them. Sergeants are (usually) smarter, are better shots, and are tougher to kill than normal Marines, though these differences in gameplay, if any, are largely unnoticed.

The UNSC Marine armor is much different in Halo 2. The utilities worn under the armor are now camouflaged. The standard issue armor is more efficient and is a rough offshoot of the original armor used by Master Chief in Halo: Combat Evolved. The Marines are less of a rag-tag group in Halo 2 than they were in Halo: Combat Evolved. They no longer wear boonie covers and are never in combat without their armor. In fact, in Halo 2, the only times Marines are seen without any armor is during the awards ceremony on the first level. In this case, they are wearing their dress whites, and one armored Marine is missing the armor for his arms. It should be noted, however, that the full gray Marine armor with additional pockets/backpack in Halo: Combat Evolved was a medical uniform, as suggested by the letters EMP (Emergency Medical Personnel) written on the back.

In the Halo Wars trailer, Marines are seen wearing helmets, balaclavas, and environmentally-suited armor to protect them from the cold.

Halo: Combat Evolved
In Halo: Combat Evolved, almost all Marines carry Assault Rifles, though occasionally they can be seen with a Sniper Rifle, Needler, Shotgun, or Plasma Rifle. They are relatively accurate with these weapons, but incidents of friendly fire sometimes occur. Marines will strafe and avoid fire but not usually seek cover. They will roll out of the way of a vehicle but they will not pick up different weapons, Health Packs, or additional ammo.

Marines are conscious of back stabbing. After you have killed three Humans of any type, the rest of the Marines in the level will attack you. If you kill Captain Keyes in The Pillar of Autumn, Cortana will lock the doors and summon a squad of invincible Marines to destroy you.

Marines hitch rides on player-driven Warthogs and Scorpions but are only capable of piloting Ghosts by themselves. They will exit Scorpions when the player leaves the driver seat, but will stay in a Warthog until they are ordered to get out. Be careful of Marines piloting Ghosts. They are occasionally prone to running you over. In Halo: Combat Evolved, the only practical way of getting a Marines' weapon, unfortunately, is by killing them.



Halo 2
In Halo 2, the Marines are much more intelligent. They are able to drive the Warthog, the Ghost, the Wraith, the Spectre and the Scorpion, albeit a bit clumsily. They can now melee sleeping Grunts or enemies with their backs turned, a vast improvement over the Halo: Combat Evolved Marines, who had to fire their weapons in such situations. The Marines are far more interactive, capable of more independent thought and wield a greater variety of weapons. The player can also easily switch weapons with the Marines to make sure that they are well armed or that the player is. As in Halo: Combat Evolved, the Marines are aware of backstabbing, and will attempt to kill you after you kill three of their comrades. They will seek cover behinds boxes and walls, though this mainly only happens when the Marines are desperate, so they don't use cover as the player does.

Halo 3
It is unknown what the Marines' armor and abilities will be in Halo 3. All that is known about them AI-wise is that they are better drivers and more capable of surviving without the player's aid. Their armor is only seen in the Halo 3 Vid-Doc Et Tu Brute?. It is the most clearly seen at the "4:54-4:57" mark in the Vid-Doc. It appears to be a slight modification of the Halo 2 Marine armor with a hint of ODST armor and seems metallic and is a blue/black color. But according to Bungie, since the Vid-Doc was made a while back that many things have changed since then. So, it is unknown what their current armor looks like.

Trivia
In the level Guilty Spark, one marine with a shotgun and fatigues will say after he kills a random flood combat form; "Hey, I knew him! That was Bob!"
 * In Halo 1, the Marine's faces were modeled on Bungie employees.
 * Bungie Studios went to great lengths to ensure that the Marines reflected the diversity of Earth; some Marines look and sound Anglo-Saxon, while others appear Asian, African, Hispanic, and Australian.
 * In the Halo: Combat Evolved level "Truth and Reconciliation", Captain Keyes tells a Marine to "Stow your belly aching...! Remember you're a leatherneck." Leatherneck was a nickname earned by U.S. Marines in the 19th century.
 * In the level Cairo Station, there is sometimes a battle damaged Marine. He is missing his helmet and is covered in blood. This is random and only happens on this level.
 * After a marine is killed in Halo 2, his/her eyes will continue to blink. (disputed)
