FA-78-2 Heavy Gundam
The evolution of the Heavy Full Armor Gundam, it had much beefier armor built into the unit as opposed to added on top, more powerful thrusters, which remedied the FA-78-1's horrid maneuverability, and omitted the Core Block System for more armor. It also received a new weapon system, the Frame Launcher, which mounted a huge Gatling gun and missile launchers. The shoulder launched rocket launcher of the FA Gundam was replaced with a much more powerful beam cannon.
Nobody here but us chickens!
