This unit was manufactured as part of the Gundam mass production plan.
As a result of being completely outsourced to various private companies, many units were born with shocking defects. The oversized generator was carried on a land-based container unit, and support AI such as the auto-balancer could not be made smaller, so the unit's main body was compressed and the cockpit was pushed forward, a mechanism that even Zeon, who managed to complete it, was surprised by. Incidentally, the cockpit was reused from the front of a fighter jet.
Naturally, accidents were frequent, and complaints arose from the field.
By the way, this does not mean that safety was neglected.
