In 1976, due to the Regent’s desire to create an indigenous Defense industry, Harad started work on creating a Haradian designed and manufactured mortar carrier.It was hoped that success with this vehicle could lead to a range of locally produced and designed equipment. In addition to this effort, licenses to locally produce foreign designs were sought, as was foreign involvement in developing Harad’s heavy industry.

The resulting APC was the the Gāmūs (or Buffalo). While originally planned to be used as a mortar carrier, it became apparent that due to the bulk of the vehicle it would be better utilized as a command or support vehicle for the 155mm SPG units of the Imperial Army.
