Civet
From Halopedia, the Halo wiki
The Civet was a military all-terrain vehicle line in service with the Colonial Military Authority and the UNSC Armed Forces, manufactured by AMG Transport Dynamics. The Civet and the Mongoose became two of the most common all-terrain military vehicles, only behind the Warthog line.[1] The vehicle line was named after the civet, a small, cat-like species of mammal.
