Anaheim Electronics developed this unit on Island 7, during the Gryps conflict. It can split in two part, like AMX-107 Bawoo, but the most important feature is DEF (hence the "Defortiterss" name). DEF is a movable AI terminal, shaped Haro-type, wich syncronize the mobile suit with the pilot, helping in navigation, firing and enemy search, in a range of about 400–700 km. It was destroyed by a MA-08 Big Zam.
