Technology & Combat Characteristics
In order to reduce costs without sacrificing general performance of their mobile suits, the Earth Federation Forces opted to simplify their existing FD-03 Gustav Karl units to maximize cost efficiency.
History
In U.C.103, several Flat Gustavs were deployed to recapture the child escapees shuttle from a secret Earth Federation Forces' Newtype research facility. During the pursuit they manage to capture the escapees shuttle, but all of them was destroyed by surprised attack from Damien Karras' JMW-07 Mono Arm.
