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. 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.

Various Insurrectionist groups have 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.

In combat, Unggoy troops will sometimes enter a berserker rage, similar to that of the Jiralhanae, but instead will brandish a pair of ignited plasma grenades and rush the enemy. Additionally, the Covenant and the Banished sometimes employed specialized units of Unggoy, called "suicide squads" by the UNSC, whose primary offensive tactic was to rush toward the enemy with a pair of ignited plasma grenades or with explosive methane canisters.

Notable incidents

 * ODST Michael Baird ingested the deadly Rumbledrugs aboard 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 Fall of Reach, Covenant suicide squads were deployed within the buildings of New Alexandria as a shock tactic against civilians and UNSC forces.
 * 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.
