A Battlefield Methane tank.

Battlefield Methane Tanks are equipment used primarily by Covenant Grunts.

The Grunt's homeworld, Balaho, is a methane-rich planet and as such they breathe methane gas. Thus, when they are in a oxygen-rich atmosphere, like that of the Halo installations or Earth, they need to wear a methane gas tank. When Grunts are in battle, they may run low on their supply of methane, so they must have a ready supply nearby if required. These tanks contain the ready supply of Methane Gas the Unggoy need.

They are short and round in shape, purple in color and have a large blue valve on the top. The Methane Tanks are seen generally where Grunts are operating. The tanks are also highly explosive due to their methane content.

Trivia

• If the blue "X" on the tank is shot at it will ignite and burn for a while before exploding.
• Battlefield Methane Tanks appear only in Halo 2. In gameplay terms, they are similar in function to Plasma batteries in Halo 3, as both explode when shot at.
• They seem to resemble Gravity Thrones that the High Prophet Hierarchs use.
