RGC-83 GM Cannon II

The RGC-83 GM Cannon II is a mobile suit from the anime OVA Mobile Suit Gundam 0083: Stardust Memory.

Combat Abilities
The GM Cannon II is heavier armed than its predecessors. It is equipped with two shoulder-mounted beam cannons, unlike the RX-77-2 Guncannon, and can carry a 90 mm machine gun as well as a beam saber for close combat. It also includes two 60 mm vulcan guns mounted in the head, but these are usually strictly last-resort weapons. To power this strong weapons the GM Cannon II has a stronger reactor. It is also very heavily armored, featuring Chobham armor based of the same design as the RX-78NT-1 Gundam "Alex". However, it pays the price for this durability with very low speed and mobility. A GM Cannon II on its own has been shown to not be able to fend for itself due to opponents being able to outmanuver it, unless its opponent also lacks speed.

History
The RGC-83 GM Cannon II is a heavy-duty support type mobile suit designed to provide covering fire for its teammates. While it is the second version of the UC 0079 RGC-80 GM Cannon, it more closely resembles the Guncannon mobile suit made famous by fighting alongside the original RX-78-2 Gundam.

Although it isn't known how many GM Cannon II models were produced it is known that two units were stationed on the Albion and used during Operation Stardust in UC 0083. The GM Cannon II was later deployed by the AEUG during the Gryps Conflict. Their units were painted forest green on gray with an orange visor.
