A mass production mobile suit used by the Human Reform League (HRL), by A.D. 2307, the Tieren Ground Type has been in service for more than a decade. It underwent several revisions through the years, but its basic structure remains unchanged. This battery driven-mobile suit made its debut in the ending stages of the Solar Power Wars, replacing the fossil fuel powered MSJ-04 Fanton. The Tieren Ground Type is considered the standard model of the Tieren series and with its excellent performance, characteristics and high versatility, it is used as the basis for developing other variants, including a space type. This again sets it apart from the Fanton, which is purely for ground use and has no space variant. There are also a small number of customized Tieren units for ace pilots.
