M69 "Barrus Kai" Heavy Ion Cannon: A D-type weapon, it was a cartridge-based beam cannon. Each cartridge had enough power to fire three shots. Compared to the later beam rifles, it was very large and unwieldy. It was used less often than the "Canus" and the "Cattus" due to its low efficiency.
The combat abilities of a single GINN was said to be equivalent to that of three to five TS-MA2 Moebius mobile armors used by the OMNI Enforcer, and it could single-handedly destroy an enemy escort ship. This led to ZAFT gaining an upper hand in the early stages of the war. Due to the GINN's excellent versatility and expandability, many variants were developed and deployed, such as the ZGMF-1017M GINN High Maneuver Type tuned for ace pilots, and the ZGMF-LRR704B GINN Long Range Reconnaissance Type for reconnaissance. Additionally, there existed GINN units customized to suit their pilots, such as the ZGMF-1017 Miguel's GINN piloted by Miguel Aiman.
