Technology & Combat Characteristics
The RB-79[M] Ball Marine Type is an aquatic variant of the RB-79 Ball (Thunderbolt Ver.) seen in the manga Mobile Suit Gundam Thunderbolt and the second season of its animated adaptation.
History
A Ball Marine Type sortied as an underwater reconnaissance unit of the Spartan while searching for Zeon Remnants. It was destroyed by an MSM-03 Gogg (Thunderbolt Ver.).
In the manga, the Ball Marine Types were later deployed in the Spartan's operations on the Rig, being used to stop evacuation crafts from leaving the Rig's surrounding waters. They were then intercepted by a Sealance high-speed watercraft, and temporarily lost the evacuation crafts. The Sealance was taken out by Alicia's GM, and the Ball Marine Types regained control of the area. Along with Bianca Carlyle's RX-77AQ Guncannon Aqua, three Ball Marine Types tried to intercept the Prober-class submarine carrying the potential pilots for the MS-06R Zaku II High Mobility Type (Reuse "P" Device). However, they were disabled after being lured into the Frizzy Yard with mines, and were unable to keep pursuing.
