'''Methane tanks''' are containers 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 their Loyalist counterparts. Instead of 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 allow Unggoy to use methane chambers 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 ==
*When shot in ''[[Halo Wars]]'' and ''[[Halo: Reach]]'', the tanks sometimes explode due to methane's high flammability.
*It is noted in the ''[[Halo 3]]'' level [[Sierra 117]] that the Jiralhanae may have added some form of addictive gas that increases the Unggoys' bravery and willingness to fight.<ref>'''[[Halo 3]]''' level ''[[Sierra 117]], Marine : "Maybe the Brutes put something in their tanks."''</ref> This is supported by 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!"). However, as the Final Grunt was meant as an easter egg, this cannot be confirmed. It is also possible that being under the Jiralhanae's leadership, who threaten to slaughter the Unggoy for meat, is responsible for their increased bravery, as suggested by [[Thel 'Vadam]].
