Suicide attack

A suicide attack is an attack intended to kill others and inflict widespread damage, in which the attacker expects or intends to die in the process. This tactic is commonly, though not exclusively, used by Unggoy troops due to their cannon-fodder status, and the general disregard for their morale by their Sangheili or Jiralhanae commanders.

Tactics
Suicide attacks have been used throughout human history. Suicidal attacks have been used since the Middle Ages. Japanese Kamikaze pilots were often assigned suicidal missions, during World War II. Suicide attacks have been used by many terrorist groups to instil fear to other people.

The Insurrectionists occasionally used suicidal tactics, including the use of "Rumbledrugs" which gave the user superhuman abilities but also caused irreversible physiological damage, often killing the user. In addition, it was not unheard of for insurgents to sacrifice themselves in terrorist bombings. The Spartan-III program was initiated to create expendable Spartan soldiers to combat the Covenant in high-risk, suicidal missions during the Human-Covenant War. Several of these missions include Operation: PROMETHEUS and Operation: TORPEDO, which both resulted in high Spartan-III casualties.

Unggoy troops will enter a "berserk" mode, similar to that of the Jiralhanae, but instead will brandish a pair of ignited plasma grenades and rush the player. Additionally, the Covenant have special units of Unggoy, called "suicide squads" by the UNSC, whose primary offensive tactic is to rush toward the enemy with a pair of ignited plasma grenades.

Notable incidents

 * Towards the end of the Battle of Mombasa, the Huragok were forced to don armor that would explode if it took too much damage, dispersing smaller charges in a wide radius.
 * During the Battle of Onyx, suicide Unggoy were successfully deployed as a diversion to distract Spartan forces as a battalion of Sangheili make ready to attack the Core of Onyx.
 * During the Battle of Installation 00, pilots of Longsword fighters too damaged to return to their ships attempted to smash their fighters into enemy ships.
 * A suicide bomber affiliated with the Freedom and Liberation Party loaded a commercial nuclear explosive along with several tons of scrap Cadmium into a rental truck before detonating it in the promenade of the Haven arcology. The blast killed two million people and injured a further 8.3 million.
 * In Casbah City, on Tribute, a female Insurrectionist detonated nearby bombs in a Jim Dandy's restaurant, killing herself. The bombing killed three Marines, and 38 civilians.
 * ODST Michael Baird ingested the deadly Rumbledrugs aboard the in order to gain the strength needed to combat boarding Covenant forces. At the bridge of the ship, he intentionally attacked the commanding Sangheili in order to get the alien to kill him. With no other humans onboard, the ship's AI, Mo Ye, was able to make the ship self-destruct to kill the Covenant forces and destroy the ship's navigation data.
 * During the Battle of Draetheus V, numerous Unggoy suicide troops were used in an attempt to breach Faraday Base's wall.

Gameplay
Occasionally during combat in Halo 3, Halo 3: ODST, Halo: Reach, and Halo 4, Grunts will enter a suicidal stage. If their leader is killed, Unggoy may sometimes activate two plasma grenades and rush to the player in an attempt to suicide-bomb them. Headshots can easily deal with these Kamikaze Unggoy if spotted quickly, but if in large numbers, or if the player does not notice them until too late, they can be a devastating force.

In Halo Wars, Suicide Unggoy are units produced by the Arbiter faction, which run at an enemy structure and ignite their gas tanks, producing an explosion greater than a grenade. This is extremely effective for destroying enemy bases while using minimal resources.

They can be upgraded to:


 * "Zeal": Speed boost while in Suicide mode.
 * "Defile": Suicide explosion does extra splash damage.
