Methane Tank
From Halopedia, the Halo wiki
Methane Tanks are cylinder shaped structures used by the Covenant.[1] They are large and resemble fuel tanks of modern trucks.
Methane Tanks are used for the Grunts of the Covenant. They provide a place for the creatures to breathe their methane atmosphere outside of their suits. Thus, Grunts usually remove their suits when entering a methane tank.[1]
If the suit is removed while the grunt is in a low-methane environment, the grunt will gasp for air (like a fish) before dying.
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.[1] These structures often have posted guards to prevent the creatures inside from being caught off guard.[2]
Halo: The Flood mentions these specifically, but in Halo: First Strike, edifices called "Methane Pits" are noticed by Spartan-104. Perhaps they are the same.
