Unggoy Heavy

"Ready for a scrap!"

- An Unggoy Heavy on Installation 00.

Heavy is a specialist combat role for Unggoy within the Covenant and its remnants.

Covenant
Heavies are designated for the use of heavy weapons, turrets, and some vehicles.

Jul 'Mdama's Covenant
These Unggoy are used to engage high-tier enemies through the use of augmented armor, explosives such as the and. This class is composed of experienced and formidable Unggoy warriors, who are often fully capable of engaging light armed vehicles effectively. Unggoy of this role are rarely encountered on the battlefield, though.

Banished
Banished Unggoy Heavies were heavily augmented by machinery on Installation 00. Like their Covenant counterparts, they focus on heavy weapon use such as s and Methane Wagons' plasma cannons. The Banished Unggoy Heavies are led by the Shadow Master of Buwan.

Covenant harnesses
The original Unggoy Heavies wore distinctive sage-green armor, typically with a full-face methane breather and a cylindrical methane tank on their back, similar to the Unggoy Ultra. Their armor provided significantly more protection than that of an Unggoy Minor or Major, but it wasn't nearly as strong as an Ultra's or a Special Operations Unggoys in terms of durability.

Slim-stock tank harness
The Heavies of Jul 'Mdama's Covenant wear a helmet with full-face protective rebreathers, enhanced optical sensors with optics articulators, and ultra-dense battle harnesses that has a slim-stock tank with analog eye sockets of Unggoy predators. The harness is issued in orange, blue, silver, green, and magenta. The combat harness also allows for the Heavies to use the methane tank as a makeshift thruster pack, allowing for easy access in various terrains.

Trivia

 * The only time a non-Heavy Unggoy is seen deploying a plasma turret is in Halo 2 at the beginning of the level The Arbiter where a Special Operations Unggoy is carrying one. This is because the only Unggoy allies encountered in the level are Special Operations units.
 * In Halo 3, if a Heavy panics while carrying an undeployed plasma turret, it will wave the turret around in the air with only one hand. This is because Unggoy usually use small single-handed weapons, and no separate animation was created for Unggoy Heavies using turrets.
 * Unggoy Heavies are classified as Special Operations Unggoy in Firefight, whereas Unggoy Ultras are simply classed as regular Unggoy. Actual Special Operations Unggoy are only seen manning the side-mounted plasma turrets on the Phantoms. Something similar happens in Halo 4, where Unggoy Heavies are classified as Ultras by the Commendations along with some other enemies who have also been mislabeled.
 * In Halo: Reach campaign level ONI: Sword Base, Unggoy Heavies are seen with s on higher difficulties.
