The RB-79K Ball Type K is a mobile pod featured in the OVA Mobile Suit Gundam: The 08th MS Team. It is piloted by Shiro Amada.
The Ball Type K is one of the earliest types produced, and is superior to later mass production types in all aspects, including armor and propellant capacity. It is a prototype of the civilian maintenance modification for full-scale mass production, and therefore retains working equipment such as lights and winches. The winch can be used for a variety of purposes by replacing the anchor, so its use on the battlefield was also explored, but it was omitted in later production models. In the cockpit, a fire control system, various radars, a communication system, and a large monitor were added, and the seats and other parts were also replaced with military equipment.
The total production capacity of the Ball Type K is less than 100, but it has been deployed to convoys and orbital security forces. In the hands of Federation pilot Shiro Amada, it recorded possibly its greatest achievement by reaching a stalemate with the MS-06RD-4 Zaku High Mobility Test Type in satellite orbit.
