A Batttlefield tank
Battlefield Methane Tanks are equipment used primarily by Covenant Grunts.
The Grunt's homeworld is a methane planet and as such they breathe methane. Thus when they are in an oxygen atmosphere like the Halos 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.
They are short and round in shape, purple in color and have a large blue valve on the top. They are seen generally where Grunts are operating. They only appear in Halo 2[1] and Halo 3 [2].
The tanks are also highly explosive due to their methane content.
