'''Methane Tanks''' are conical, cylindrical, pyramidal, and in some cases, saggy-ended cone structures used by [[Covenant Empire|Covenant]] [[Unggoy]], fixed onto their [[Unggoy Combat Harness|Combat Harness]].<ref name="beer">'''[[Halo: The Flood]]''', page 60</ref>

==Description==
Methane tanks are back mounted, moderately large, and resemble small fuel tanks of modern trucks. When they are of the large variety, they provide a place for the creatures to breathe their [[methane]] atmosphere outside of their suits. Thus, Grunts remove their suits when entering the huge methane filled tank, as they are not needed.<ref name="beer"/>

===Heretic variant===
The tanks of [[Heretics|Heretic]] Grunts look quite different from the Loyalist counterparts. Instead being pyramid, or curved pyramid-shaped, they are two tube-shaped ones, with visible smaller tubes that connect it to their mouthpiece in which they breath the methane from.

==Methane chambers==
The Covenant also created special "Methane chambers" for grunts when they are not in battle. There is a main chamber for the Grunts to reside in and a smaller chamber in front where the Grunts can change into and out of their suits.<ref name="beer"/> These structures often have posted guards to prevent the creatures inside from being caught off guard, and airlocks on their entrances.<ref>'''[[Halo: The Flood]]''', page 61</ref> A number of different types of methane chamber exist, the [[Atmosphere Pit]], which a more temporary version, and the [[Methane Suite]], a ship-board variant.

== Trivia ==
*It is interesting that the [[Unggoy]]s' methane tanks explode quite easily when hit by Human projectile bullets. The most likely reason the Covenant didn't reinforce the methane tanks is due to the low status of the Grunts within their social hierarchy.
*When shot in ''[[Halo Wars]]'', the tanks sometimes explode due to methane's high flammability. Sometimes if you shoot the gas tank, you can see blue gas seep out. In fact if you destroy all methane tanks in mission 2 of Halo Wars you get the "[[Endless Fun]]" achievement.
*In ''[[Halo: Reach]]'', when a Methane Tank is shot off, it will send the Grunt flying through the air. There is also more variety in the tank designs between different Grunt ranks.<ref>[http://www.youtube.com/watch?v=yyWmnbni02U&feature=player_embedded '''YouTube''': ''Halo Reach Firefight 2.0 Gameplay Footage'']</ref>
*It was also noted in the ''[[Halo 3]]'' level [[Sierra 117]] that the Brutes may have added some form of addictive gas that increases their bravery and willingness to fight, similar to steroids.<ref>'''[[Halo 3]]''' level ''{{Levelname|Sierra 117}}, Marine : "Maybe the Brutes put something in their tanks."''</ref> If this is true then the [[Final Grunt]]'s words ("...it's the gas. When I'm on the gas, I don't know what I'm doing half the time!") make sense. However, as the Final Grunt was meant as an easter egg, this cannot be confirmed. However, it can explain why the grunts are braver. However, this can also be because of the Brute's threats to slaughter them for meat that rallied them, as suggested by [[Thel 'Vadam]].
