Methane Tank

Methane Tanks are cylindrical, pyramidal, and in Halo: Combat Evolved, cones that curl-at-the-ended structures used by Covenant Unggoy (Grunts). They are moderately large and resemble small fuel tanks of modern trucks.

When they are really huge, 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.

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. These structures often have posted guards to prevent the creatures inside from being caught off guard.

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.

It is interesting that the Unggoy's methane tanks explode so easily when hit by Human projectile bullets, one would think the Covenant would have considered there tanks being hit by Super-Heated Plasma and would have reinforced them against such an accident. It may be that those who designed the suits wanted to keep Unggoy population under control, but this is still shaky since the explosion of flame could endanger other soldiers as well, it could also be blamed on production costs and how unimportant the Unggoy's role in combat was anyway. It seems that some grunts are addicted to the methane (which is unlikely, since it is what they always breath) or that an addictive substance is place in the tanks.
