The standard mass production mobile suit of the Human Reform League. The Tieren is a relatively old model that has been in service for more than a decade, and its mobility is limited by its weight and bulk. However, it is heavily armed and armored, and its technology is highly reliable. Many variations of the Tieren exist, but they all use the same standard control system, in which data and external images are projected onto the inside of the pilot's helmet. This ground type is equipped with a shell-firing gun, a carbon blade for melee combat, and a leg-mounted shield that protects its lower body from enemy fire.
